Question

Which trigonometric values equal 0? Check all that apply.

A. sin(3π)
B. cos(–360°)
C. tan(900°)
D. Cosine (negative 5π/2)
E. cot(0°)

Answer 1

The trigonometric values that equal 0 are sin(3π) and Cosine (negative 5π/2).

Step-by-step explanation:

To determine which trigonometric values equal 0, we can evaluate each trigonometric function at the given angles.

A. sin(3π) = 0 because sine of any multiple of π is 0.

B. cos(–360°) = 1 because cosine of any multiple of 360° is 1.

C. tan(900°) = undefined because tangent is undefined at 900°.

D. Cosine (negative 5π/2) = 0 because cosine of any odd multiple of π/2 is 0.

E. cot(0°) = undefined because cotangent is undefined at 0°.
