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: Find the particular solution of the differential equation http://cwcsrv11.cwc.psu.edu/webwork2_files/tmp/equations/f3/6548289ff6de84dd65caa37d658bfa1.png [Broken] http://cwcsrv11.cwc.psu.edu/webwork2_files/tmp/equations/b1/8df613430b792391dbdebef80a9c361.png [Broken] http://cwcsrv11.cwc.psu.edu/webwork2_files/tmp/equations/b3/33fc13f666a02da7144a5fb4c3dd661.png [Broken] = ? 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?
