   8 Μαΐ 2013 · Lecture Notes Trigonometric Identities 1 page 4 6. cos2 x = cscxcosx tanx+cotx Solution: We will start with the right-hand side. We will re-write everything in terms of sinx and cosx and simplify. We will again run into the Pythagorean identity, sin2 x+cos2 x = 1. RHS = cscxcosx tanx+cotx = 1 sinx cosx sinx cosx + cosx sinx = 1 sinx cosx 1 sin2 ...
