Handwrit/e and show all work and steps

Honors Precalculus Module 5 Project - Show your work for any calculations needed or simplifications made! - Clearly show your work and the steps necessary to prove an identity or to solve an equation. "Exact" solutions mean rational expressions not decimals the calculator returns! 1: Jr 1. Find the exact value of cos[ + Z)by using trigonometric identities to rewrite and simplify. 2. Verify the identity sin(A B)sin(A + B) = sin2 A sin2 B. 3. Use trigonometric identities and algebra to find exact solutions tan(x + 7) - cos x + ~ =0. Give all solutions on the interval [0,25) 4. Given that sin A = _, , cos B = - -, and that both A and B are in quadrant II, find cos(A - B). Simplify it to a single value, leaving it in exact form
