Ok, I'm barely understanding proofs and have caught a snag, I need your guy's help on this question:
(1-cos^2x)(cscx) = sinx I keep getting 1 for the left side as an answer.

Working on the left side the next step would be making (1-cos^2x) become sin^2x. Then you convert cscx to 1/sinx and then you get sin = sin.

Oh ok, I get it now, took me a bit to figure where you got sinx from sin2x, anyway, thank you
