## Homework Statement

Evaluate the following integral:

(int)1/sqrt(2x-x

^{2})dx

## Homework Equations

d(arcsinx)/dx = 1/sqrt(1-x

^{2})

## The Attempt at a Solution

I just need a good start in the right direction on this one so I can at least try it. I know the arcsin d/dx as above, but how do I make this work? Is it some kind of integration by parts or reduction? I have no idea how to go about dealing with the sqrt(2x-x

^{2}) mostly, or how it would get there from arcsin...

any help you can give would be much appreciated!
