3 我们可以调用“数学面板”进行输入，写好的代码直接复制过来，是这样子滴：\[Integral]Sqrt[x + Sqrt[x]] \[DifferentialD]x//FullSimplify//TraditionalForm 这里对结果先化简（FullSimplify），后化形（TraditionalForm），然后再作积分函数与原来的函数的图像，加以比较：Plot[{Sqrt[x + Sqrt[x]],%}...
WolframAlpha["int -(t-Tanh[t])Sech[t]^2Tanh[t] over t",IncludePods->"IndefiniteIntegral",AppearanceElements->{"Pods"},PodStates->{"IndefiniteIntegral__Step-by-step solution"}] 输出结果如下, 虽然说有很多步骤它给得太详细了, 但是按着这个路子, 很容易就可以算出来了. 也许以后再也不怕算积...

In step 1, you need to use the command f[x_] to create a function; you need to set several expressions at the same time;In the second step, you need to find the definite integral -Integrate[f,{x,xmin,xmax}] and the commonly used function NMaximize[f,x];figure 1 figure 2 In ...
It can be at least as difficult to compute a fractional derivative as an integral. ButFractionalDcan still often do it though the result can quickly become quite complicated: Why isFractionalDa separate function, rather than just being part of a generalization ofD? We discussed this for quite ...
