Question

Solve by variation of parameters. I'm so close on this... I just got to put it in the correct format.
y''+y=cscx

Answer 1

answer is y=(c1-x)cosx+(c2+ln(sinx))sinx
I got these terms in separate areas...do I combine them?

Answer 2

like that? since if yh = c1cosx+c2sinx and yp = -xcosx+ln(sinx)sinx?
then yh+yp

Answer 3

and factor

Answer 4

@phi

Answer 5

yes, the complete solution is y = yp + yh

Answer 6

which you can write as you posted:
y=(c1-x)cosx+(c2+ln(sinx))sinx
