# Math Help - proving identities basic

1. ## proving identities basic

Hi, I would just like to confirm i have the correct answer before I move on.

sinx + tanx = tanx (cosx + 1)

I found both sides equal 2sinx.......

2. With identities you should work only on one side and get it to equal the other:

From the RHS $\tan(x)\cos(x) + \tan(x) = \sin(x) + \dfrac{\sin(x)}{\cos(x)} = \sin(x) + \tan(x)$
