【Abstract】 The problem of derivative of function with integral variable limit is an important part of the combination of integral and derivative operation. The key to solve the problem is to find a fast and effective computing method. The problem is solved by multivariate composite functions. When the derivatives are solved,they can be solved respectively by the integrating variational limits and derivatives variables in the integrand. This method can solve the problem of derivative of function with integral variation easily and effectively,and students can easily grasp it and accurately apply it.更多还原
