10.7.23 Calculating integrals of a real variable using residues
Condition: \( \mathrm{C} \) calculate the integral using residues. \[ I_{3}=\int_{-\infty}^{+\infty} \frac{4 x^{2}-8 x+7}{\left(x^{2}+12 x+37\right)\left(x^{2}+16 x+68\right)} \]
Here you can find calculations of proper and improper integrals of a real variable using residues, using various techniques.
