1. ## trigonometric identity

Hello, i was wondering if anyone could help me with this identity. cosθ + sinθtanθ = 1/cosθ. I've only started learning these and i'm already stuck on this one. I cannot figure it out, could someone show me the solution perhaps, or a nudge in the right direction, thank you.

Hint: write $\tan(\theta)=\frac{\sin(\theta)}{\cos(\theta)}$ and get a common denominator on the left hand side.
