Prove the identit: cosxcotx+sinx=cscx
Answered by visoth
1) rewrite cosx (cosx/sinx) + sinx = csc x

2) cosx^2/sinx + sinx = csc x

3) multiply sinx by (sinx/sinx) to get same denominator

this gives you cosx^2/sinx + sinx^2/sinx = cscx

4) combine your fractions

(cosx^2 + sinx^2)/sinx = cscx

5) rewrite numerator

1/sinx= csc x

and there you go it is proven (you have to know your trig identity to do this so look them up if you don't know them)
