Question

Test each of the following identities by first evaluating both sides to see that they are numerically equal when u 12 and v 43 Then let u x and u 22 and compare the graphs of each side of the identity as functions of x in degrees For example in part a graph one of y sin x 22 or y sinx cos22 sin22 cosx for 360 x 360 Round your answers to 3 decimal places a sin u v sinu cosu sinu cosu b sin u v sinu cosu c cos u v cosu Cosu sinu cosu sinu sinu d cos u v cosu Cosu sinu sinu
