almost EVERYTHING in one integral

6:24

method 2 is NICE!

14:03

Gaussian Integral [Int{e^-x^2} from -inf to inf]

17:18

towards the notion of an exact second order differential equation

6:22

an interesting integral

4:48

Don't blame BMT! I messed this one up : (

5:08

Weird problem!

The Gaussian Integral is DESTROYED by Feynman’s Technique
