## Examples From Inside Interesting Integrals by Paul Nahin: Part 4

Part 1 Part 2 Part 3 This is part 4/4 of a review by example of Inside Interesting Integrals by Paul Nahin. Here, we will use two methods to solve problem C8.8: $$\int\limits_{-\infty}^{\infty} \frac{x^{2}}{(x^{2}+a^{2})^{3}} dx = \frac{\pi}{8a^{3}}$$ for … Continue reading
