## Homework Statement

y" + y = 2/sin(x)

solve for y

## Homework Equations

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
