PreCalculus Module 5 DBA 40 points Be sure to show and explain all work. 10 points each 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: 2cos x = 4 cos x sin x Answer: 2cos x = 4 cos x sin x 2cos x = 4 cos x sin x (2 cos x in common onboth sides) 1 = sin x The only place sin x = 1 is where the angle is ?. X = 2 Part 3 - Discussion Question Is it possible to factor 1 - sin x two different ways? If so, show and explain. If not, why not
