Simplify Numerator and DenominatorDate: 4/15/96 at 21:15:5 From: "Scott A. Mehring" Subject: Derivatives of sines and cosines What is the algebra, or actually the trig, that lets you go from -sin x + 1 ----------- (1- sin x)^2 to 1 ----- 1-sin x You take one -sin x from the top out of the den, but how is it done in a step-by-step process? Thank you.
