On Solution of the Double Integral via Polar Coordinate Transformation
The key to the difficulty of double integration calculation is to make appropriate transforma-tions to the integration region and the expression of the integrand function,which facilitates the simplifica-tion of the solving process.For double integrals containing x2+y2,the curves and integrands in the inte-gration region are respectively standardized,and then solved using polar coordinate transformation.It is found that calculating double integrals using standardized integrands is better than calculating double inte-grals using standardized integration regions.
