In this class, you'll learn how to evaluate lots of interesting integrals, many of which require clever tricks! For example, we will derive these very strange results: $$\int_{-\infty}^{\infty} e^{-x^2} = \sqrt{\pi}$$ and $$\int_{-\infty}^{\infty} \frac{\cos(x)}{4x^2 + 1}dx = \frac{\pi}{2\sqrt{e}}.$$ This class is mostly lecture but will have a few pauses where you can try out the techniques that you learn.
