Part 1 - Application

Find your own values that prove that tan(u-v) tan u - tan v. Show your work and explain why you chose these values.

Part 2 - Find the error(s) and solve the problem correctly. Explain your corrections.

Solve for 2cos x = 4 cos x sin ^2x

Answer: 2 cos x= 4 cos x sin ^2x

2 cos x = 4 cos x sin ^ 2 x (2 cos x is common on both sides)

sin x =1 and angle is pi/2.

x=pi/2

Part 3 - Discussion Question

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