sin(2x)=1. Take the inverse sine of both sides of the equation to extract from inside the sine. The exact value of is . Divide each term by and simplify. Feb 04, 2010 · Thus (1 + sinx + cosx)(1 - cosx) = sinx(1 + sinx - cosx). Now divide both sides by (1 + sinx - cosx)(1 - cosx) to arrive at the desired identity.

cosx(1+sinx) / cos^2x. get rid of the cosx on top by simplifying and the cos^2x so that you're left with (1+sinx) / cos x. Therefore cosx / 1- sinx = 1 + sinx / cos x We have to prove that :((sin x + cos x)/(sin x - cos x)) + ((sin x - cosx)/(sin x + cos x)) = (2*sec^2x/tan^2x) - 1 ((sin x + cos x)/(sin x - cos x)) + ((sin x - cosx By multiplying both numerator and denominator by #1+sinx # and using the difference of squares the result follows quickly.
