Thank you all. I was on the right track.I must be just overstressed atm not to see something so obvious. I got it now.

No, we haven't learned the power reduction formula but it sounds a lot easier Hydrargyrum. I will look into it and continue trying. I did sub Pi/4 in for x on both side ofthe equation and yes they are =. So back to proving again, Thanks EV1 for the help.

You are correct it is not. I was trying to prove that the equation on the left is = to the equation on the right in the beginning of the post. Could I simplify the equation on the right anymore that might = cos^2x -sin^2x??

Hello this one has stumped me for about a day and I have tried several different approaches. maybe someone could point me in the right direction. cot^2x-1/1+cot^2x=2Cos^2x-1 I startedon the Left side tring to prove the equation. cot^2x-1/csc^2x using Pyth. Theory...
