Divide 0 0 by 1 1. Hint The appearance of 1 + cos x 1 + cos x suggests we can produce an expression without a constant term in the denominator by substituting x = 2t x = 2 t and using the half-angle identity cos2 t = 12(1 + cos 2t) cos 2 t = 1 2 ( 1 + cos 2 t). Using complement or cofunction identity, cosx = sin(π/2 - x) sinx + cosx = sinx + sin(π/2 - x) · Hence, dividing by cosx ≠ 0, sinx cosx = 1, or,tanx = 1. ∙ xa2 −b2 = (a −b)(a +b) ⇒ sin2x − cos2x sinx + cosx.
