You can also 1-cos^2x/1-sinx= -sinx Trigonometry - Damon, Monday, May 30, 2011 at 6:43pm assume you mean (this took some serious detective work - please be careful with parentheses) 2015-05-05 Since, [math]cos2x=cos^{2}x-sin^{2}x[/math] [math]1-cos2x=1-(cos^{2}x-sin^{2}x)[/math] [math]1-cos2x=1-cos^{2}x+sin^{2}x[/math] We know, [math]sin^{2}x+cos^{2}x=1 cos(2x) = cos 2 (x) – sin 2 (x) = 1 – 2 sin 2 (x) = 2 cos 2 (x) – 1 Half-Angle Identities The above identities can be re-stated by squaring each side and doubling all of the angle measures. Cos2x is a double angle trigonometry that has the espansion of cos2x = cos^2 (x) -sin^2 (x) but you know that sin^2 (x) + cos^2 (x) = 1.
