Question

simplify tan^2x/(cscx+1)

Answer 1

Do you know the trig identity:

\[\Large \tan^2\alpha + 1 = \sec^2\alpha \]

Answer 2

yes sir

Answer 3

Try \( \tan^2 = \sec^2x - 1 \) as the basis of a substitution.

Answer 4

oops i messed up its supposed to be tan^3x over cscx+1

Answer 5

i ended up with 2tan(x) thanks a lot !
