Study on the Problem of Limit defination
Of multivariable Integral
Abstract
Multivariable Integrals is an important content of multivariable function integration.Its calculation thoughts is tun the multivariable integral into repeated integrals, to be definite the lpper limits and inferior limit are always both important and difficult during learning and teaching of multivariable Integrals.In this paper,we discuss the Projection at axise of space curves and cuble and based on different case of integral field.we introduce special methods to determine the limit of Double integral, the determined of Triple integrals ,graph determined mehods ,combine algebric analysis and plane gragh mehods.
Key words::Projection;Double Integral;Triple Integral;Repeated Integral;Bounds of Integrals
