Physics 68 Lagrangian Mechanics (7 of 25) Simple Harmonic Motion: Method 2

Visit http://ilectureonline.com for more math and science lectures! In this video I will use method 2 to derive the position with-respect-to time and frequency equation of a simple pendulum problem using the partial derivative of Lagrangian equation.
