Question

find a cofunction with the same value as the given expression. sin 8° select the correct choice below and fill in the answer box to complete your choice. (simplify your answer. type any angle measures in degrees. do not include the degree symbol in your answer.) a. sin 8° = cot b. sin 8° = tan c. sin 8° = csc d. sin 8° = sec e. sin 8° = cos

Explanation:

Step1: Recall co - function identity

The co - function identity for sine and cosine is $\sin\theta=\cos(90 - \theta)$.

Step2: Substitute $\theta = 8$

When $\theta = 8$, we have $\sin8^{\circ}=\cos(90 - 8)^{\circ}=\cos82^{\circ}$.

Answer:

E. $\cos82$
