Trig / Pre Cal/identities Am I on the right path? Please do not give the answer. Here is the problem $$\frac{(\sin x- \cos x)*2}{cos} = \sec x - \cos x$$ I am working on the left side and need to prove it equals the right. This is what I have done so far $$\frac{(\sin^2 x - 2(\cos x)(\sin x)+\cos^2 x}{\cos x} = \sec x - \cos x$$ Am I going about this the right way because I don't see where to go from here. Thank you.
