Trigonometric integral problem

Click For Summary
SUMMARY

The discussion focuses on solving the integral \(\int\frac{1+\sqrt{\cos x}}{\sin x} \, dx\). The user initially breaks down the integral into two parts: \(\int \csc x \, dx\) and \(\int \frac{\sqrt{\cos x}}{\sin x} \, dx\). A suggested substitution of \(\sqrt{\cos x} = a\) simplifies the expression, allowing the use of partial fractions to complete the solution. This method effectively resolves the integral problem presented.

Homework Statement


\int\frac{1+\sqrt{cosx}}{sinx} Hi , I really need a help for this


Homework Equations





The Attempt at a Solution



\int\frac{1+\sqrt{cosx}}{\sqrt{sin}\sqrt{sin}}

\int\frac{1}{sinx} + \int\frac{1}{\sqrt{sinx}}\sqrt{}\frac{cosx}{sinx} =

\int cscx + \int\sqrt{cscx cotx} = ?

\int cscx is alright but i have no idea for second part .

do you have any idea ?

Make the substitution \sqrt{cosx}=a Then simplify the resulting expression, use partial fractions and you're done.
 
Yes that's it! thanks for your help...
