Second Order Linear Differential Equations
www.personal.psu.edu › sxt104 › class
In general, given a second order linear equation with the y-term missing y″ + p(t) y′ = g(t), we can solve it by the substitutions u = y′ and u′ = y″ to change the equation to a first order linear equation. Use the integrating factor method to solve for u, and then integrate u to find y. That is: 1. Substitute : u′ + p(t) u = g(t) 2.
