We can evaluate the double integral by integrating with respect to each variable one by one according to their order in the integration term . After integrating with respect to one variable , we have to apply its limit and then we can perform integration using next variable .
The following integration formulas can be used here ,
Consider the double integral
Where can be written as using the conversion formula of radical to exponent
The expression can be written as by taking to the numerator.
Thus we can write the integral as
First we have to integrate with respect to x by taking y terms outside as a constant.
Use the formula
