There aren't any inverse functions here?

2. wio

oops, nevermind.

$\sec(x)=\frac{1}{\sin(x)}$ and$\tan(x)=\frac{\sin(x)}{\cos(x)}$replace and then do algebra

4. Atkinsoha

It's a multiple choice, sorry I thought the rest of the question posted. It says, determine which of the following is NOT equivalent. cos^2Ø-sin^2Ø csc^2Ø -cot^2Ø 1 sec^2Ø -tan^2Ø sin^2Ø +cos^2Ø
