MATH 211 - Differential Equations & Linear Algebra Whole CH5 Explanation

CORRECTION AT 1:11:26 It should be yh = C1 + xC2 because r1 = 0 and r2 = 0 which are repeated roots One last thing I forgot to mention in the concept of the mass-spring system is that you should also expect a question where an external force is applied on the block and you won't have a 0 on the RHS of the differential equation. So you could have one of the 3(exp,trig,poly) and you will use method of undetermined coefficients to find Yh and Yp and add them together and then apply initial conditions.
