Doing the following integral

  • #1

Main Question or Discussion Point

I haven't done basic integrals for awhile...but just wondering how you would integrate the following functions without looking it up in the integral table.

(x^2+a^2)^(-3/2) where a is a constant.

Thanks!

Make the substitution [itex] x=a\sinh t [/itex] and then see what you get.

The substitution [itex]x= atan(\theta)[/itex] will also work.
