Prove this trigonometric identity... I dare you!!

Please help!. alabama high school homework... trigonometric identity

Change both the sides of the equation to sines and cosines and you should be able to find it out from their

The identity is incorrect, so it can't be proven. I suspect that the identity you are trying to prove is actually this:


\frac {sec(x)-csc(x)} {sec(x)+csc(x)} = \frac {\tan(x) -1}{\tan(x) + 1}


As Phabio said - convert the functions to sine and cosine equivalents and work from there.
