On the Double Integral Calculation Methods and Techniques
Abstract: The basic way to calculate the double integral is first of all to translate it into computing quadratic integral, or repeated integral, focusing on how to make the process more simple calculation. By exploring the double integral problem-solving method, the paper summarizes several calculation methods of double integrals: variable substitution, polar coordinate transformation, rotation symmetry coordinate translation transform, and refers to a large number of examples detailed exposition of how to make use of "smart" the method for solving the effect of the "wonderful" and summarized.
