    Re: Verify the following identity (show EVERY step)

    cosx/(1-sinx) = cos x ( 1+sinx) /[(1-sinx)(1+sinx)] = cos x ( 1+sinx) /(1-sin^2x) = cos x ( 1+sinx) /cos^2x = (1+sin x )/ cos x = 1/cosx + sin x / cos x = sec x + tan x

    I find it rude to be ordered to show every step when the OP has not shown any effort to do a single step him/herself...
