多重积分计算方法小结

AbstractThe form of multiple integral is various.Mastering calculation methods isthe key to solve problems.This paper mainly discusses several calculationmethods of double integral and triple integral,from every aspects such asrectangular coordinates,coordinate transformation,symmetry,integration by parts,converting curvilinear integral or surface integral and so on,meanwhile giving some examples respectively.This paper morecomprehensively summarizes the calculation methods of multiple integral,andanalyzes the common errors in the use of various methods,hoping to providecertain reference for beginners.Keywords:double integral;triple integral;calculation methods
