LHS = [cos^2(x)]/sin(x) + sin(x) Put these two terms under a common denominator. Since the sin(x) is really divided by 1, our LCD would be sin(x), resulting in: LHS = [cos^2(x)]/sin(x) + [sin^2(x okay this problem stumped me for a while but here is my work for it, and I just got stuck at the end so if any help can be provided thanks in advance. sin3x = sinx sin(2x + x) = sinx sin2x cos x + cos2x sinx = sinx 2sinx cosx cosx + (2cos^2(x) -1) sinx = sinx 2sinx cos^2(x) + 2007-11-26 · sinxtanx=secx-cosx. sinxtanx=1-cos^2x/cosx.
