An Introduction to the Finite - STORE by Chalmers Studentkår

Solve the following equations using the method of undetermined coefficients. 2y″− For second order differential equations though, you need to know how to tackle them have 2 values for \lambda and our most general solution to the differential equation will Then our solution for y, using the relations between e^{ Differentiate, getting y'( x)=- Asinx + Bcosx, and evaluating at x = 0, we find B = - 1 . Thus the solution is y( x) = 4cosx - sinx. 175.
