Ch3Pr33c: 2nd order ODE without guessing - YouTube
Sep 6, 2015 ... Or why there are two constants? In this video we split a second order ODE into two first order ODEs. This is an alternative method solves Chapter ...

Example 17.6.1 Solve the differential equation ¨y−˙y−6y=18t2+5. The general solution of the homogeneous equation is Ae3t+Be−2t. We guess that a solution ...
Now our approach to solving an equation of the above type is a simple one: we guess a solution. Of course, its an educated guess, there's a lot of maths behind ...

Solve a nonhomogeneous differential equation by the method of
The idea here is to realize that (ycosx)′=y′cosx−ysinx so the equation becomes (y′+ycosx)′=0⇒y′+ycosx=c1. Now you can use the integranting factor ...
This fact and the second equation imply that B=-1/2. If the nonhomogeneous term is a polynomial of degree n, then an initial guess for the particular ...
