SUMMARY

The integral $\int \frac{1}{(a+x^2)\sqrt{2a+x^2}}\,dx$ can be solved using Euler substitution. Specifically, the substitution $\sqrt{2a + x^{2}} = x - t$ simplifies the expression, allowing for easier integration. This method effectively transforms the integral into a more manageable form, facilitating the solution process.

It's been a while since I've done much integration, could someone please give me a hint with:

[tex]\int \frac{1}{(a+x^2)\sqrt{2a+x^2}}\,dx[/tex]

Thanks

Use Euler substitution:

[tex] \sqrt{2a + x^{2}} = x - t[/tex]
 
Thanks :)
