1.) Find your own values that prove that tan(u-v) tan u - tan v. Show work and explain why these values were chosen.

2.) Find the error(s) and solve the problem correctly. Explain the corrections. Solve: 2cos x = 4 cos x sin²x

Answer: 2cos x = 4 cos x sin ²x 2cos x = 4 cos x sin ²x(2 cos x in common onboth sides)

1 = sin ²x

The only place sin x = 1 is where the angle is 2

x = 2

3.) Is it possible to factor 1 sin ²x two different ways? If so, show and explain. If not, why not?
