ODE - Solving Non Homogeneous ODEs of Sine/Cosine with Euler's Relation

Here is a super useful trick that allows you to solve Non-Homogeneous ODEs where g(x) is a sine or cosine much faster than the standard method. In undetermined coefficients, we turn our problem from a sine and cosine territory into exponential territory, which is much more simple. 00:00 Example 1 y''+4y'+4y=3cos(2x) 10:48 Example 2 y''+2y'+2y=8sin(3x) ODE series video 8 I hope you got what you came for!
