New to the forums (Obviously)

I'm having slight trouble with a problem relating to the volume of a rotating region R, but I only need help with the integral of the function itself.

I have $\displaystyle \int\frac{1}{\sqrt{3x-x^2}},dx$

I am required to use partial fractions and obviously substitution for the problem so no integral calculator answers please. I can work it out once I have the partial fractions used in solving.
