Question: Make a conjecture. Choose the correct answer below. | A. cos4x sin4x = (cosx)? * B. cos^x - sin^x= cosx C. cosx- sin x

Make a conjecture. Choose the correct answer below. | A. cos4x sin4x = (cosx)? * B. cos^x - sin^x= cosx C. cosx- sin x = cos 2x OD. cosx- sin x = (cos 2x) Apply a cofunction identity. Apply an even-odd identity. Verify this conjecture algebraically. To do so, start with the more co transform the expression at each step. Apply a Pythagorean identity. cos 4x - sin x = (cos 2x - sin 2x) (cos 2x + sin 2x) II Apply the sum identity for cosine.
