Here, we show you a step-by-step solved example of improper integrals. This solution was automatically generated by our smart calculator:
Solve the integral by applying the formula $\displaystyle\int\frac{x'}{x^2+a^2}dx=\frac{1}{a}\arctan\left(\frac{x}{a}\right)$
Add the initial limits of integration
Replace the integral's limit by a finite value
Evaluate the definite integral
Evaluate the arctangent of $0$
Multiply $-1$ times $0$
$x+0=x$, where $x$ is any expression
Apply the limit $\lim_{x\to\infty}\arctan(x)=\frac{\pi}{2}$
Evaluate the resulting limits of the integral
