Math Help - Trig identities.

1. Trig identities.

show that two waveforms represented by V1 = sec(SQUARED) + cosec(SQUARED) and V2 = sec(SQUARED)x.cosec(SQUARED) are interchangeable.

2. Re: Please help guys,,im struggling!!!

Use the fact that $\sec^2(x)=\frac{1}{\cos^2(x)}$ and $\csc^2(x)=\frac{1}{\sin^2(x)}$

You're meant to make the suggested substitutions and then make an effort. Where do you get stuck?

Then I suggest the old-fashioned approach - Apply what you have learned and do it by hand using algebra. Show all your work, say where you get stuck.
