ODE - Section 5.2 - Vibrations of a mass on a spring - Free, Undamped Motion

This video explains how to solve spring-mass problems (free, undamped motion case). It also explains how to get the period, frequency, and correct way to calculate phase angle; also explains how to rewrite solution into a single trig function that is physically meaningful.

Stumbled across this vid and I do not regret it. Finally learning from someone who does not skip steps like my lecturer. Thank you man.
