So this equation came up:
xy' + y = cos x
Now I was just wondering how to solve this, all I've learned how to do is separation of variables, which cannot be used in this case.
Basically I ask this because a solution for y is an infinite series, so basically I'm just wondering if the infinite series converges to some function of x, and if it does which function is it?
