Applicare la formula: $\int\frac{n}{a+b}dx$$=n\int\frac{1}{a+b}dx$, dove $a=1$, $b=x^2$ e $n=5$

Applicare la formula: $\int\frac{n}{x^2+b}dx$$=\frac{n}{\sqrt{b}}\arctan\left(\frac{x}{\sqrt{b}}\right)+C$, dove $b=1$ e $n=1$

Applicare la formula: $\left[x\right]_{a}^{b}$$=eval\left(x,b\right)-eval\left(x,a\right)+C$, dove $a=1$, $b=\sqrt{3}$ e $x=5\arctan\left(x\right)$
