We will evaluate the improper integral 1-e^(-1/x^2) from 0 to infinity. This integral actually converges thanks to the "1-". This integral is closely related to the most famous integral in the world, the Gaussian integral. In fact, we can use integration by parts, u-substitution, and L'Hosptial's rule to make the connection with the Gaussian integral. #calculus #mathforfun #blackpenredpen
