Web( cos x) ( sin x) − x sin 2 x + x cos 2 x. My main issue is cleaning this up to get the derivative to equal 1 2 sin 2 x + x cos 2 x. I am not quite sure where the change from x to 2x came from. I know it's probably some old trig rules that I have forgotten. So if anyone could help with the simplification that would be great!
