# How to get this integral into standard form

1. Nov 18, 2011

If I have the definite integral of 1/sqrt(c2-dv2) (without a dv after it), with c a real positive constant larger than the upper limit of the integral, how can I get it into the usual form of an integral f(v) dv ?

What you have written makes no sense at all. Can you give the context? Where did you see
$$\int \frac{1}{\sqrt{c^2- dv^2}}$$
