Hi Everyone!(adsbygoogle = window.adsbygoogle || []).push({});

I just need some guidance on this problem. I seem to have trouble what integration technique I need to use on integrals of this type.

1. The problem statement, all variables and given/known data

integrate 1/(25-x^2)

2. Relevant equations

sqrt(a^2-u^2)

arcsin(u/a)

3. The attempt at a solution

Would I be able to use trig substitution for this type of integral? It almost fits with the arcsin but the square root is missing.
