摘要
针对利用莱布尼茨公式在求某些函数n阶导数时无法得出通项公式的问题,本文采用三角形公式及欧拉公式解决了指数函数与三角函数相乘的n阶求导问题,并给出相应的例子。
This paper found the problem that the general formula cannot been gotten of n - order derivatives calculated by Leibniz formula, dealt with calculation in n - order derivatives of multiplication of exponential function and triangles function by Euler formula and triangle formula, and provided respective examples.
