1. ## Trig Proof

Need some help on this one. Just not sure where to go, used Sum to Product. That just confused me even more. If someone could show me a couple of step that would be great. thanks.

2cosΘ+sin2Θ = 2cos^3Θ/ 1-sinΘ

2. $2cosx +sin(2x) = 2cosx+2sin(x)cos(x) = 2cosx(1+sinx)$

Then multiply

$2cosx(1+sinx)$ by $\dfrac{(1-sinx)}{(1-sinx)}$
