Take note that this angle is in the fourth quadrant. This means that the only the cosine/secant of this angle is positive.
First, find the reference angle.
Then, write down the six trigonometric functions of the original angle:
I will leave the evaluation for you.
- If angle is in first quadrant, all trigonometric functions are positive
- If angle is in second quadrant, only sine/cosecant are positive
- If angle is in third quadrant, only tangent/cotangent are positive
- If angle is in fourth quadrant, only cosine/secant are positive
