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

Daniel.
 
Can you be more specific please?
 
Transform the integral (make a change of variable).

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

x=2\arctan t

Daniel.
 
hello there

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

see what you could do with that if it helps
