Integral

[lostinhere]

I'm having trouble with this. Can anyone help me integrate

sqrt(2+2sin(x))

??

Thanks

sqrt(2+2sin(x))
Can you out it into a different form first?

Other than
sqrt(2)*sqrt(1+sin(x))

I'm stuck

HINT:Make the substitution

\tan\frac{x}{2}=t

Can you be more specific please?

[dextercioby]

Transform the integral (make a change of variable).

\sqrt{2}\int \sqrt{1+\sin x} \ dx

x=2\arctan t

hello there

sqrt[1+sinx]=[(cosx)^2]/[sqrt[1-sinx]]

see what you could do with that if it helps
