Welcome to the awesome 12-part series on the Gaussian integral. In this series of videos, I calculate the Gaussian integral in 12 different ways. Which method is the best? Watch and find out!

In this video, I calculate the Gaussian integral by using a Fubini-type argument, namely by calculating the volume under the 3d bell curve in 2 different ways.

Note: This series of videos is based on Keith Conrad’s notes, which can be found here: http://www.math.uconn.edu/~kconrad/blurbs/analysis/gaussianintegral.pdf
