【Abstract】 Triple integral is an important knowledge point in higher mathematics teaching, especially the calculation of triple integral in spherical coordinate system. One of the teaching difficulties of triple integral in spherical coordinate system is how to understand volume calculus clearly and intuitively. Different from the abstract theoretical analysis method of coordinate transformation, the analysis process of triple integral volume differential formula in spherical coordinate system is given intuitively and vividly from the perspective of volume increment and MATLAB drawing.更多还原
