\[ \int\sqrt{1+\sqrt{x}+\sqrt{1+2\sqrt{x}+2x}}\,\mathrm{d}x \]
  1. Integrate[Sqrt[1 + Sqrt[x] + Sqrt[1 + 2*Sqrt[x] + 2*x]], x]
Copy the Code

这种基本上都是系数比较特殊的情况,也就是凑巧能积出来。如果改变其中一些系数,估计就无法积出来了。
\[\frac{2 \sqrt{\sqrt{2 x+2\sqrt{x}+1}+1} \left(6 x^{3/2}+\sqrt{x}+\left(\sqrt{x}-2\right) \sqrt{2 x+2\sqrt{x}+1}+\sqrt{x}+2\right)}{15 \sqrt{x}}\]
