how would you varify the following
sinx+sinx cot^2x=cscx

Answered by Steve
The same way you do any of these proofs. Start using the trig identities you know, to transform one side of the equation till it matches the other side. I used to love these identity proofs when I studied trig. It was amazing how many ways there were to write the same things!

Do lots of them. It will stand you in good stead later on.

But I digress.

sin + sin cot^2
sin (1 + cot^2)
sin(csc^2)
1/csc * csc^2
csc
