## Homework Statement

solve the following equation using method of intergrating factors:

## Homework Equations

dy/dx = y + cosx - sinx

## The Attempt at a Solution

i think i have to get it in the form dy/dx + r(x)y = f(x)

but i can't see how,

if i multiply or divide by a factor i won't have dy/dx on its own. and how do i identify what's f(x) and r(x)?

i also tried

dy + (-y -cosx +sinx)dx = 0

and then just finding a factor to make it an exact differntial, but I am not sure how i determine the factor.
