Question

I need help proving a few trigonometric identities.


`tanA = tanA * cscA^(2) + cot(-A)`


`csc^(2) \beta -csc^(2) \beta *sec^(2) \beta = -sec^(2) \beta`


`cscx+cotx=(sinx)/(1-cosx)`


`(secx+tanx)^(2) = (cscx+1)/(cscx-1)`

Answer 1

i have solved them . if u can't understand. .. ask me XD
