In response to the problem that the existing triple integral calculator is unable to calculate the double integral, this paper improves the triple integral calculator. Firstly, the input modes for users to calculate the dual and triple integrals are introduced respectively. Secondly, a method is designed to transform the dual integral input mode into an equivalent triple integral input mode. Finally, the method of calculating the dual integral with the triple integral calculator is designed. The experimental results show that the improved ...
