Sympy无法计算积分secx + 1** 2，x

如何解决Sympy无法计算积分secx + 1** 2，x

我感到奇怪的是，const closeUploader = () => { //Todo: Destroy created filepond instance } 不能评估sympy却可以评估integrate(sec(x+1)**2,x)。我已经限制了integrate(sec(x)**2,x)的域，以防万一，但我仍然无法评估`sec（x + 1）** 2的积分。

x

为什么sympy对此感到挣扎？

解决方法

这可以说是SymPy中的错误，但是您可以通过重写sec来解决：
