y" + y = 2/sin(x)
solve for y
I tried to use variation of parameters to solve this but I don't know how to check it.
The Attempt at a Solution
y = -2xcosx + (constant)cosx + 2ln(sin(x))sinx + (constant)sinx
How do I do this using Undetermined coefficients? I can't find a basis for the null space of 2/sinx
