Chapter 6.2, Problem 106AYU

To determine

To find: $g\left(-\theta \right)$

Answer to Problem 106AYU

Solution:

  $g\left(-\theta \right)=\frac{1}{2}$

Explanation of Solution

Given:

  $f\left(\theta \right)=\sin \theta , g\left(\theta \right)=\cos \theta \text{and} \theta =60°$

Calculation:

  $g\left(-\theta \right)=\cos \left(-\theta \right)=\cos \theta =\cos 60°=\frac{1}{2}$
