Need help to find the particular integral of a 2nd order diffn eqn using Euler's eqn ;
I know that there are other methods of solution. Just want to understand the principle (Euler's) that i'm trying to apply to my type of solution.
By Euler's eqn
This is where i'm uncertain,
because question has on RHS
1) Should the Real part be included seeing that the question has the imaginary part (sin4x) only?
- Replace D with coefficient of x in
My final answer wasn't correct. Seek help using my method and not another approach.
