# Homework Help: Integration of (x)/[(4-x^2)^0.5]

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

(x)/[(4-x^2)^0.5]

2. Relevant equations

3. The attempt at a solution

which method would be used to integrate this, or is it just a standard integral from a regular standard integral table, so can be integrated directly? The book seems to indicate it is a standard integral, but I can't seem to locate it.

I can see a similar standard integral which is

(1)/[a^2 - x^2]^0.5

though this is 1 over, and the question is x over.

Thank you

A simple u-substitution would work quite well here.
