y dx + x ln x dy = 0 ; x > 0
my integrating factor is x..
so.. multiply with DE,
xy dx + x^2 ln x dy = 0
let M = xy ; N = x^2 ln x
dM/dy = x ; dN/dx = x + 2x ln x
the problem is.. i didn't get the exact equation after multiply the integrating factor.. i've double checked my integrating factor.. but.. still can't get the exact equation...
