integral

Find the integral of this function
\(\displaystyle \int\frac{5}{\sqrt 9-x^2}dx\)

Here is my work
5 arcsin (x)/3 +c
I'm not sure if it is right

The correct one is:

\(\displaystyle \frac{-5\sqrt{3}ln(\frac{\sqrt{3}x-3}{\sqrt{3}x+3})}{6}\)

I think this is the intended integral ...

\(\displaystyle \int \frac{5}{\sqrt{9-x^2}} \, dx\)
