Hello everyone, Another diff EQ problem, he gave us like 100. I can't seem to figure what method to use on this one. I tried seperable but that isn't working. Here it is:(adsbygoogle = window.adsbygoogle || []).push({});

Find the particular solution of the differential equation

dy = (7*cos(x)-y*cos(x))dx;

theres no way i can get it so dx is on 1 side and dy on the other.

if its using integrating factor i'm also stuck because what would be p(t)?

y' + ycos(x) = 7cos(x);

would i let p(t) = y? then

solve using that method? But i always thought it had to be a function of x? so would it be

p(t) = cos(x)?

then do i integrate e^(cos(x)) and get e^(sin(x)) as the integrating factor?
