Convert the radical to an exponent. Then use the form

*u*.^{power}du

Use the form for one of the inverse trig. functions.

If

, then you need to add a. In this case, it would be. Since you already have a, add ataking out a to compensate. Multiply

.

Then take the antiderivative.

Take the antiderivative.
