I meant to say prove sorry about that.

The problem I have with this problem is that I don't know how to change

into a different form.

Its just the fact thats its in an equation and I just don't know where to start. - Mar 8th 2010, 10:54 AMmr fantastic

I know the definitions:

csc x = 1/sinx

sec x = 1/cosx

Cot= cosx/sinx

But once I put them into the equation I dont know what to do. - Mar 8th 2010, 11:20 AMmr fantastic
