1. What is the reference angle for-30$^\circ$?

Explanations: The reference angle for an angle is the smallest angle it makes with the x-axis. For -30°, we first convert it to a positive equivalent by adding 360°: -30° + 360° = 330°. The reference angle for 330° is found by subtracting it from 360°: 360° - 330° = 30°.

Option Analysis:

Option A: Incorrect, as the reference angle should be 30°.
Option B: Incorrect, as it is not related to the reference angle of -30° or its equivalent positive angle.
Option C: Incorrect, as the reference angle for -30° is not 60°.
Option D: Correct, as explained above.

2. If $\tan \theta = 1$ $\cot \theta$

Explanations: The reciprocal of $\cot \theta$ is $\tan \theta$. Given that $\tan \theta = 1$, the reciprocal, which is $\cot \theta$, must be $1$.

Option Analysis:

Option A: Undefined. Not applicable here as we have a defined value for $\tan \theta$.
Option B: -1. Incorrect, the reciprocal of 1 is not -1.
Option C: 1. Correct, since $\cot \theta = \frac{1}{\tan \theta}$ and $\tan \theta = 1$, then $\cot \theta = 1$.
Option D: 0. Incorrect, the reciprocal of a non-zero number cannot be zero.

3. Given the Cos(x) =-2/3, then the Sec(x) =?

Explanations: Given that $\cos(x) = -\frac{2}{3}$, we need to find the value of $\sec(x)$. The secant function is the reciprocal of the cosine function, so $\sec(x) = \frac{1}{\cos(x)}$. Substituting the given value: \[ \sec(x) = \frac{1}{-\frac{2}{3}} = -\frac{3}{2} \]

Option Analysis:

Option A: Incorrect. Cosine is not equal to $-\frac{2}{3}$.
Option B: Incorrect. This value does not match the reciprocal of $\cos(x)$.
Option C: Correct. The reciprocal of $-\frac{2}{3}$ is $-\frac{3}{2}$.
Option D: Incorrect. Cosine and secant are reciprocals, so the sign must be preserved.

4. Secant is the reciprocal of what function?

Explanations: Secant is the reciprocal of Cosine. This means that $\sec(x) = \frac{1}{\cos(x)}$.

Option Analysis:

Option A: Sine - Incorrect, as secant's reciprocal is cosine, not sine.
Option B: Tangent - Incorrect, as tangent is the ratio of sine to cosine, not related to secant directly.
Option C: Cosine - Correct, because $\sec(x) = \frac{1}{\cos(x)}$.
Option D: Cosecant - Incorrect, as cosecant is the reciprocal of sine, not cosine.

5. Which of the following statements is true for all $\theta$

Explanations: The correct answer is B) $\cot \theta = \frac{\cos \theta}{\sin \theta}$. This statement is true for all $\theta$ where $\sin \theta \neq 0$. The cotangent function, by definition, is the reciprocal of the tangent function, which can be expressed as the ratio of cosine to sine.

Option Analysis:

Option A: This statement is incorrect because secant is the reciprocal of cosine, not tangent.
Option B: Correct as explained above.
Option C: Incorrect; secant is the reciprocal of cosine, not sine.
Option D: Incorrect; cosecant is the reciprocal of sine, not cosine.

6. What is the reciprocal of the sine function?

Explanations: The reciprocal of the sine function is the cosecant function. This means that if $ \sin(x) = y $, then $ \csc(x) = \frac{1}{y} $.

Option Analysis:

Option A: Secant is the reciprocal of cosine, not sine.
Option B: Cosecant is indeed the reciprocal of sine. This is correct.
Option C: Cotangent is the ratio of cosine to sine, not their reciprocals.
Option D: Cosine is the reciprocal of secant, which is the reciprocal of cosine, not sine.

7. What is the value of $\sec\left(\frac{\pi}{3}\right)$

Explanations: The value of $\sec\left(\frac{\pi}{3}\right)$ is $2$. This can be determined by recalling that the secant function is the reciprocal of the cosine function, i.e., $\sec(x) = \frac{1}{\cos(x)}$. For $x = \frac{\pi}{3}$, we know that $\cos\left(\frac{\pi}{3}\right) = \frac{1}{2}$. Therefore, $\sec\left(\frac{\pi}{3}\right) = \frac{1}{\cos\left(\frac{\pi}{3}\right)} = \frac{1}{\frac{1}{2}} = 2$.

Option Analysis:

Option A: Correct.
Option B: Incorrect.
Option C: Incorrect.
Option D: Incorrect.

8. Given the Cosec x = 1, then the Sin x =?

Explanations: Given that Cosec x = 1, we know that Sin x is the reciprocal of Cosec x. Therefore, if Cosec x = 1, then Sin x must be 1 .

Option Analysis:

Option A: -1. Incorrect as Sin x cannot be negative when Cosec x is positive.
Option B: 0. Incorrect as Sin x would only be zero if the reciprocal (Cosec) were undefined or infinite, which it isn't here.
Option C: Undefined. Incorrect because Cosec x = 1 is defined and has a clear reciprocal value for Sin x.
Option D: 1. Correct as the reciprocal of 1 is 1, meaning Sin x = 1 when Cosec x = 1.

9. What is the reference angle for $\frac{4\pi}{3}$

Explanations: The reference angle for an angle in standard position is the smallest angle that the terminal side of the given angle makes with the x-axis. For $\frac{4\pi}{3}$, this angle lies in the third quadrant. The reference angle can be found by subtracting $\pi$ from $\frac{4\pi}{3}$: $\frac{4\pi}{3} - \pi = \frac{4\pi}{3} - \frac{3\pi}{3} = \frac{\pi}{3}$. Thus, the reference angle for $\frac{4\pi}{3}$ is $\frac{\pi}{3}$.

Option Analysis:

Option A: Incorrect. $\frac{\pi}{4}$ does not represent the smallest angle between the terminal side of $\frac{4\pi}{3}$ and the x-axis.
Option B: Correct. As calculated, the reference angle is indeed $\frac{\pi}{3}$.
Option C: Incorrect. $\frac{\pi}{6}$ does not represent the smallest angle between the terminal side of $\frac{4\pi}{3}$ and the x-axis.
Option D: Incorrect. $\frac{7\pi}{6}$ is an angle in the third quadrant, but it is not the reference angle for $\frac{4\pi}{3}$.

10. What is the value of $\csc\left(\frac{\pi}{2}\right)$

Explanations: The value of $\csc\left(\frac{\pi}{2}\right)$ is $1$. The cosecant function, $\csc(x)$, is the reciprocal of the sine function, $\sin(x)$. At $x = \frac{\pi}{2}$, $\sin\left(\frac{\pi}{2}\right) = 1$. Therefore, $\csc\left(\frac{\pi}{2}\right) = \frac{1}{\sin\left(\frac{\pi}{2}\right)} = 1$.

Option Analysis:

Option A: Incorrect. The value is not $0$.
Option B: Incorrect. The value is not $-1$.
Option C: Incorrect. The function is defined at $\frac{\pi}{2}$.
Option D: Correct. The value of $\csc\left(\frac{\pi}{2}\right)$ is $1$.

11. In which quadrant is-570$^\circ$

Explanations: To determine the quadrant in which $-570^\circ$ lies, we first need to find an equivalent angle between $0^\circ$ and $360^\circ$. We do this by adding $360^\circ$ repeatedly until we get a positive angle. Starting with $-570^\circ$, we add $360^\circ$: \[ -570^\circ + 360^\circ = -210^\circ \] Since $-210^\circ$ is still negative, we add another $360^\circ$: \[ -210^\circ + 360^\circ = 150^\circ \] Now, the angle $150^\circ$ lies in the second quadrant.

Option Analysis:

Option A: IV. Incorrect; $-570^\circ$ is equivalent to $150^\circ$, which is in the second quadrant.
Option B: II. Correct; as explained, $150^\circ$ lies in the second quadrant.
Option C: I. Incorrect; $-570^\circ$ does not lie in the first quadrant.
Option D: III. Incorrect; $-570^\circ$ is equivalent to $150^\circ$, which is in the second, not third, quadrant.

12. What is the value of $\csc\left(\frac{3\pi}{2}\right)$

Explanations: The value of $\csc\left(\frac{3\pi}{2}\right)$ is $-1$. This is because the cosecant function, which is the reciprocal of the sine function, evaluates to $\frac{1}{\sin\left(\frac{3\pi}{2}\right)}$. At $\frac{3\pi}{2}$, the sine value is $-1$; thus, $\csc\left(\frac{3\pi}{2}\right) = \frac{1}{-1} = -1$.

Option Analysis:

Option A: 1. Incorrect as the sine of $\frac{3\pi}{2}$ is $-1$, making the cosecant value $-1$.
Option B: Undefined. Incorrect, since $\sin\left(\frac{3\pi}{2}\right)$ exists and is non-zero.
Option C: -1. Correct as explained above.
Option D: 0. Incorrect as the sine of $\frac{3\pi}{2}$ is not zero, making the cosecant value non-zero.

13. Which of the following angles in radians makes $\cot \theta$

Explanations: The cotangent function, $\cot \theta$, is defined as the reciprocal of the tangent function: $\cot \theta = \frac{1}{\tan \theta}$. The tangent function, $\tan \theta$, has vertical asymptotes at $\theta = \frac{\pi}{2} + k\pi$ for any integer $k$, meaning it is undefined at these points. At these values of $\theta$, the cotangent function will be zero because its reciprocal would be undefined. - Option A ($\frac{3\pi}{2}$): This value makes $\cot \theta = 0$ since $\tan \left( \frac{3\pi}{2} \right)$ is undefined. - Option B ($\pi$): This value also makes $\cot \theta = 0$ because $\tan \pi = 0$. - Option C (0): This value does not make $\cot \theta = 0$; instead, it would be undefined since $\tan 0 = 0$, and the reciprocal of zero is undefined. - Option D ($\frac{\pi}{2}$): This value makes $\cot \theta$ undefined because $\tan \left( \frac{\pi}{2} \right)$ is undefined. Thus, the correct answer is C) $0$.

Option Analysis:

Option A: $\frac{3\pi}{2}$: Makes $\cot \theta = 0$ because $\tan \left( \frac{3\pi}{2} \right)$ is undefined.
Option B: $\pi$: Makes $\cot \theta = 0$ since $\tan \pi = 0$.
Option C: $0$: Does not make $\cot \theta = 0$; undefined because $\tan 0 = 0$.
Option D: $\frac{\pi}{2}$: Makes $\cot \theta$ undefined since $\tan \left( \frac{\pi}{2} \right)$ is undefined.

14. Find $\csc\left(\theta\right)$ $\cos\left(\theta\right)=\frac{4\sqrt{17}}{17}$ $\sin\left(\theta\right)<0$

Explanations: The reciprocal trigonometric function of sine is cosecant, so $\csc(\theta) = \frac{1}{\sin(\theta)}$. Given that $\cos(\theta) = \frac{4\sqrt{17}}{17}$, we can use the Pythagorean identity to find $\sin(\theta)$: $\sin^2(\theta) + \cos^2(\theta) = 1$. Substituting the given value, we get: \[ \sin^2(\theta) + \left(\frac{4\sqrt{17}}{17}\right)^2 = 1 \] \[ \sin^2(\theta) + \frac{16 \cdot 17}{289} = 1 \] \[ \sin^2(\theta) + \frac{16}{17} = 1 \] \[ \sin^2(\theta) = 1 - \frac{16}{17} \] \[ \sin^2(\theta) = \frac{1}{17} \] Since $\sin(\theta) < 0$, we take the negative square root: \[ \sin(\theta) = -\sqrt{\frac{1}{17}} = -\frac{1}{\sqrt{17}} = -\frac{\sqrt{17}}{17} \] Thus, $\csc(\theta) = \frac{1}{\sin(\theta)} = \frac{1}{-\frac{\sqrt{17}}{17}} = -\sqrt{17}$.

Option Analysis:

Option A: $\frac{1}{4}$ is incorrect as it does not match the derived value.
Option B: $-4$ is incorrect as it does not match the derived value and the reciprocal of a fraction with $\sqrt{17}$ in the denominator cannot be an integer.
Option C: $-\sqrt{17}$ is correct, matching our calculation.
Option D: $\frac{\sqrt{17}}{17}$ is incorrect as it represents $\sin(\theta)$, not $\csc(\theta)$.

15. Cotangent is the reciprocal of what function?

Explanations: Cotangent is the reciprocal of tangent. This means that for any angle in a right triangle, the cotangent of the angle is equal to the cosine of the angle divided by the sine of the angle, which simplifies to the adjacent side over the opposite side (the definition of tangent's reciprocal).

Option Analysis:

Option A: Correct. Cotangent is indeed the reciprocal of tangent.
Option B: Incorrect. Sine and cotangent are not reciprocals; their product equals cosine.
Option C: Incorrect. Cosine and cotangent are related but not reciprocal functions in this sense.
Option D: Incorrect. Cosecant is the reciprocal of sine, not tangent.

16. Find $\tan\left(\theta\right)$ $\sin\left(\theta\right)=-\frac{3}{5}$ $\cos\left(\theta\right)>0$

Explanations: Given that $\sin(\theta) = -\frac{3}{5}$ and $\cos(\theta) > 0$, we can determine the value of $\tan(\theta)$ using the identity $\tan(\theta) = \frac{\sin(\theta)}{\cos(\theta)}$. Since $\sin(\theta)$ is negative and $\cos(\theta)$ is positive, $\theta$ must be in the fourth quadrant where tangent (which is sine over cosine) will also be negative. Given $\sin(\theta) = -\frac{3}{5}$, we can find $\cos(\theta)$ using the Pythagorean identity: $\sin^2(\theta) + \cos^2(\theta) = 1$. Plugging in the value of $\sin(\theta)$: \[ \left(-\frac{3}{5}\right)^2 + \cos^2(\theta) = 1 \] \[ \frac{9}{25} + \cos^2(\theta) = 1 \] \[ \cos^2(\theta) = 1 - \frac{9}{25} \] \[ \cos^2(\theta) = \frac{16}{25} \] Since $\cos(\theta) > 0$, we take the positive square root: \[ \cos(\theta) = \frac{4}{5} \] Now, using the identity for tangent: \[ \tan(\theta) = \frac{\sin(\theta)}{\cos(\theta)} = \frac{-\frac{3}{5}}{\frac{4}{5}} = -\frac{3}{4} \]

Option Analysis:

Option A: $\frac{4}{3}$ is incorrect as it does not match the calculated value.
Option B: $-\frac{3}{4}$ is correct based on the calculation above.
Option C: $-\frac{5}{3}$ is incorrect as it does not match the calculated value and would imply a different sine value.
Option D: $\frac{4}{5}$ is incorrect as it does not match the calculated value and represents cosine, not tangent.

17. What is sin$^{-1}$(1/2)?

Explanations: The function $\sin^{-1}(x)$ represents the angle whose sine is $x$. For $\sin^{-1}\left(\frac{1}{2}\right)$, we need to find an angle $\theta$ such that $\sin(\theta) = \frac{1}{2}$. In the unit circle, the sine of an angle corresponds to the y-coordinate. The angles in the first and second quadrants where $\sin(\theta) = \frac{1}{2}$ are $30^\circ$ (or $\pi/6$ radians) and $150^\circ$ (or $5\pi/6$ radians). However, the range of the inverse sine function is restricted to $[-90^\circ, 90^\circ]$, which means we only consider the first quadrant angle. Thus, $\sin^{-1}\left(\frac{1}{2}\right) = 30^\circ$.

Option Analysis:

Option A: Incorrect. The angle is not 150 degrees.
Option B: Correct. $\sin^{-1}\left(\frac{1}{2}\right) = 30^\circ$.
Option C: Incorrect. The angle is not 60 degrees.
Option D: Incorrect. The angle is not 120 degrees.

18. Given the Csc(x) = 1, then the Sin(x) =?

Explanations: Given that Csc(x) = 1 , we can use the reciprocal relationship between sine and cosecant functions, which states that Csc(x) = $\frac{1}{Sin(x)}$ . Therefore, if Csc(x) = 1 , then Sin(x) = $\frac{1}{Csc(x)} = \frac{1}{1} = 1$ .

Option Analysis:

Option A: Undefined. Incorrect, as the reciprocal relationship directly gives us a defined value.
Option B: -1. Incorrect, as sine cannot be negative if cosecant is positive (which it is in this case).
Option C: 0. Incorrect, as sine cannot be zero if cosecant is one.
Option D: 1. Correct, based on the reciprocal relationship between sine and cosecant functions.

19. In what kind of triangle can you use SOH-CAH-TOA?

Explanations: SOH-CAH-TOA is a mnemonic used to remember the definitions of sine, cosine, and tangent in trigonometry. These functions are specifically defined for right triangles, where one angle is always 90 degrees. Therefore, SOH-CAH-TOA can only be applied to right triangles.

Option Analysis:

Option A: Correct. SOH-CAH-TOA applies exclusively to right triangles.
Option B: Incorrect. The mnemonic does not apply to any kind of triangle.
Option C: Incorrect. The mnemonic cannot be used for non-right triangles, even if they are acute or obtuse.
Option D: Incorrect. There is a correct answer among the options provided.

20. Which reciprocal trigonometric function is undefined at $\theta = \pi$

Option Analysis:

Option A: sec \theta = \frac{1}{\cos \theta} is defined at \theta = \pi because cos(\pi) ≠ 0.
Option B: Correct, as csc(\pi) is undefined due to sin(\pi) = 0.
Option C: cot \theta = \frac{\cos \theta}{\sin \theta} is defined at \theta = \pi because cos(\pi) ≠ 0 and sin(\pi) = 0 does not make the numerator zero.
Option D: Incorrect, as B is correct.

21. Which of the following is the reciprocal of $\tan \theta$

Explanations: The reciprocal of $\tan \theta$ is $\cot \theta$. This is because the definition of cotangent ($\cot \theta$) is the reciprocal of tangent ($\tan \theta$), which can be expressed as: \[ \cot \theta = \frac{1}{\tan \theta} \]

Option Analysis:

Option A: Correct. $\cot \theta$ is indeed the reciprocal of $\tan \theta$.
Option B: Incorrect. Sine ($\sin \theta$) is not related to the reciprocal of tangent.
Option C: Incorrect. Secant ($\sec \theta$) is the reciprocal of cosine, not tangent.
Option D: Incorrect. Cosine ($\cos \theta$) is not involved in the reciprocal relationship with tangent.

22. If $\sin \theta = \frac{\sqrt{3}}{2}$ $0 < \theta < \pi$ $\csc \theta$

Explanations: The reciprocal of the sine function is the cosecant (csc) function, so $\csc \theta = \frac{1}{\sin \theta}$. Given that $\sin \theta = \frac{\sqrt{3}}{2}$, we can find $\csc \theta$ by taking the reciprocal of $\frac{\sqrt{3}}{2}$, which is $\frac{2}{\sqrt{3}}$. To rationalize the denominator, multiply both numerator and denominator by $\sqrt{3}$ to get $\frac{2\sqrt{3}}{3}$.

Option Analysis:

Option A: Incorrect. It does not match the calculated value.
Option B: Correct. This is the rationalized form of the reciprocal of $\sin \theta$.
Option C: Incorrect. It is a common trigonometric value but not the correct answer here.
Option D: Incorrect. It is equal to $\sin \theta$ and not its reciprocal.

23. Find a coterminal angle to-27$^\circ$.

Explanations: To find a coterminal angle to $-27^\circ$, we add $360^\circ$ (a full rotation) to the given angle until we get an equivalent angle within the desired range. Adding $360^\circ$ to $-27^\circ$ gives us: \[ -27^\circ + 360^\circ = 333^\circ \] However, this is not one of the options provided. Instead, we can subtract $360^\circ$ from $-27^\circ$ to find a negative coterminal angle within the range: \[ -27^\circ - 360^\circ = -387^\circ \] This matches option B.

Option Analysis:

Option A: $-393^\circ$ is not a coterminal angle to $-27^\circ$ because it does not result from adding or subtracting $360^\circ$.
Option B: $-387^\circ$ is correct as shown above.
Option C: $27^\circ$ is not a coterminal angle to $-27^\circ$ because it does not share the same terminal side.
Option D: $323^\circ$ is not a coterminal angle to $-27^\circ$. Adding or subtracting $360^\circ$ from $-27^\circ$ does not yield this result.

24. What is the value of $\sec(\pi)$

Explanations: The value of $\sec(\pi)$ is $-1$. This is because the secant function, which is the reciprocal of the cosine function ($\sec(x) = \frac{1}{\cos(x)}$), evaluates to $\frac{1}{\cos(\pi)}$. Since $\cos(\pi) = -1$, it follows that $\sec(\pi) = \frac{1}{-1} = -1$.

Option Analysis:

Option A: 1 is incorrect because $\cos(\pi) = -1$ and the reciprocal of $-1$ is $-1$, not $1$.
Option B: $-1$ is correct as explained above.
Option C: Undefined is incorrect because $\cos(\pi) = -1$ and the reciprocal of a non-zero number is defined.
Option D: 0 is incorrect because it would imply that $\cos(\pi)$ equals zero, which it does not; $\cos(\pi) = -1$.

25. If $\theta = \frac{\pi}{4}$ $\cot \theta$

Explanations: The cotangent function is the reciprocal of the tangent function, i.e., $\cot \theta = \frac{1}{\tan \theta}$. Given that $\theta = \frac{\pi}{4}$, we know that $\tan \left(\frac{\pi}{4}\right) = 1$. Therefore, $\cot \left(\frac{\pi}{4}\right) = \frac{1}{1} = 1$.

Option Analysis:

Option A: Incorrect. The value of $\cot \theta$ at $\theta = \frac{\pi}{4}$ is not zero.
Option B: Incorrect. The value of $\cot \theta$ at $\theta = \frac{\pi}{4}$ is not -1.
Option C: Correct. As calculated, $\cot \left(\frac{\pi}{4}\right) = 1$.
Option D: Incorrect. The value of $\cot \theta$ at $\theta = \frac{\pi}{4}$ is not $\sqrt{2}$.

26. What is the reference angle for 125$^\circ$?

Explanations: The reference angle for an angle in standard position is the smallest angle that the terminal side of the given angle makes with the x-axis. For an angle of $125^\circ$, which lies in the second quadrant, we subtract it from $180^\circ$ to find the reference angle: \[ 180^\circ - 125^\circ = 55^\circ \]

Option Analysis:

Option A: 75$^\circ$. Incorrect. This would be the supplementary angle, not the reference angle.
Option B: 55$^\circ$. Correct. The calculation shows this is the reference angle for $125^\circ$.
Option C: 235$^\circ$. Incorrect. This angle is in the third quadrant and not related to the reference angle of $125^\circ$.
Option D: 125$^\circ$. Incorrect. The given angle itself does not represent its reference angle.
