Differential Eequations, Lecture 5.4: Laplace transforms of periodic functions.

In this lecture we use geometric series to compute the Laplace transform of a periodic function in terms of the Laplace transform of its "fundamental window." As an example, we solve an ODE for simple harmonic motion when the forcing term is a square wave.

Hi Prof, where and how do you get 2 over 1+e^-s. it confused me. Thanks
