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.
