In order to use u-substitution, we have to think about what would be an appropriate u. As the denominator of the integrand has a form of something over square root of something minus something (that contains x) squared, the integrand has a form of the derivative for inverse sin. In order to use this derivative, I will modify the integrand.
*Note: Please ignore the grey area right next to the integration sign.
Hi,
