Integrating sin(2x)/(1+sin x)

[eay444]

Homework Statement

integrate: sin (2x)/(1+sinx)

Homework Equations

(sin x)^2 + (cos x) ^2 = 1
sin (2x) = 2 sin x cos x
cos (2x) = (cos x)^2 - (sin x)^2

The Attempt at a Solution

I've been trying to integrate this thing for about an hour by rearranging various trig idenities with no luck. Am I missing something? I don't think this problem is supposed to be that hard. Someone please help!

I would try first replacing sin (2x) with 2 sin x cos x then do u sub and let u = cos x. Try that and see if it helps
