The integrand is an expression with unbalanced parentheses. Please correct it post the correct expression to be integrated.Please find the integration of:
[math]\int \frac{(cos^2(a+b)cos(a)}{x} dx[/math]
Where,
[math]cos(a) = \frac{r^2+R^2-x^2}{2rR}[/math]and
[math]cos(b) = \frac{r^2+x^2-R^2}{2rx}[/math]
Thank you for your help.
Thank you Zermelo for your suggestionHi there, you should read the guidelines and understand that we’re not allowed to solve your problems, or help you before seeing your work. You need to show us what you did first, and where you’re stuck.
I personally would look up the formula for cos(x + y) if I were you, then the numerator should (eventually) simplify to a polynomial.
You have to show us what you did and EXACTLY where you are stuck.Thank you Zermelo for your suggestion
Yes, I did it the same way, but after that, it is a long calculation to get the result and difficult to do that. Actually, I am stuck from the beginning of my work.

First thing you need to do is to correct your original post.
Then show us how you had used expansion of cos(x + y) and what did you do after that - even if you know that it is incorrect.
