Find the simplest expression for each of the questions sec^2theta(1-cos^2 theta) and sin^2 theta cos theta + cos^3 theta I would appreciate it if you could show working thanks Last edited: May 16, 2010

sec^2 x (1-cos^2 x) 1/cos^2 x (sin^2 x) tan^2 x sin^2 x cos x + cos^3 x cos x (sin^2 x + cos^2 x) cos x
