The Calculation And Application of Integral in Polar Coordinates
Abstract: Firstly, this paper gives the related concept of definite integral and double integral. Then we make some studies and summaries on the methods of calculation of double integral in polar coordinates based on the previous work and use examples to verity the effectiveness of the proposed methods according to the different methods of calculation. Finally, the applications of definite integral and double integral in geometry and physics are given.
