Question

rewrite sin 20.6° in terms of its coluncion. sin 20.6° = (type an exact answer. simplify your answer. type any angle measures in degrees. do not include the degree symbol in your answer.)

Explanation:

Step1: Recall cofunction identity

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

Step2: Apply the identity to $\sin20.6^\circ$

Substitute $\theta = 20.6$ into the identity: $\sin20.6 = \cos(90 - 20.6)$.
Calculate $90 - 20.6 = 69.4$. So $\sin20.6^\circ=\cos(69.4)$.

Answer:

$\cos(69.4)$
