Chapter 6.2, Problem 103AYU

To determine

To find: $2f\left(\theta \right)$

Answer to Problem 103AYU

Solution:

  $2f\left(\theta \right)=\sqrt{3}$

Explanation of Solution

Given:

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

Calculation:

  $2f\left(\theta \right)=2\sin \theta =2\sin 60°=2\times \frac{\sqrt{3}}{2}=\sqrt{3}$
