In this video we'll learn how to use the method of undetermined coefficients to find the particular solution to the second-order nonhomogeneous differential equation. In order to do this, we'll have to first find the complementary solution. Then we'll make a guess about the particular solution, take its first and second derivatives, and then plug those back into the original differential equation in order to solve for the coefficients in the particular solution. The sum of complementary and particular solutions will be the general solution of the differential equation.

Hi, I’m Krista! I make math courses to keep you from banging your head against the wall. ;)

Math class was always so frustrating for me. I’d go to a class, spend hours on homework, and three days later have an “Ah-ha!” moment about how the problems worked that could have slashed my homework time in half. I’d think, “WHY didn’t my teacher just tell me this in the first place?!”

So I started tutoring to keep other people out of the same aggravating, time-sucking cycle. Since then, I’ve recorded tons of videos and written out cheat-sheet style notes and formula sheets to help every math student—from basic middle school classes to advanced college calculus—figure out what’s going on, understand the important concepts, and pass their classes, once and for all.
