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

Use the fact that $\displaystyle \sec^2(x)=\frac{1}{\cos^2(x)}$ and $\displaystyle \csc^2(x)=\frac{1}{\sin^2(x)}$
youre the best siron,,but how do i write it?

sorry like,,but tbh i dont know how to edit cosec into the calc for a start!
