10.7.27 Calculating integrals of a real variable using residues
Condition: Calculate the integral using residues: \[ \int_{-\infty}^{+\infty} \frac{1}{\left(x^{2}+2\right)^{2}\left(x^{2}+10\right)^{2}} d x \]
Here you can find calculations of proper and improper integrals of a real variable using residues, using various techniques.
