Chapter 33: Second Order Differential Equations



Such equations arise naturally in physics since Newton's equations of motion involve acceleration which is a second derivative.
We make some brief comments about such equations, show how they can be solved numerically with a spreadsheet, and discuss two specific examples: the forced harmonic oscillator (which also describes the behavior of an R L C circuit) and planetary motion.
