∴ the given differential equation is of order 1 and degree 1. By dividing through out by e^(y) and taking z=e^(-y), we can reduce the eqn to a linear first order eqn in z and x. Solution is 2x. e^(-y)+C.x^(2)=1 M(x,y) dx + N(x,y) = 0 We're looking to make this an exact equation, because if we do, it can be solved rather systematically. In order to be exact, by claurait's theoem (think that's the name of it, though not sure on spelling).
y = xln|x| + Ax We can write the equation (x+y)dx-xdy = 0 as: " " xdy = (x+y)dx :. dy/dx = (x+y)/x :. dy/dx = 1+y/x :. dy/dx - 1/x y = 1 This is a First Order DE of the form: y'(x) + P(x)y = Q(x) Which we know how to solve using an Integrating Factor given by: IF = e^(int P(x) \ dx) And so our Integrating Factor is: IF = e^(int -1/x \ dx) \ \ \ \ = e^(-ln|x|) \ \ \ \ = e^(ln|1/x|) \ \ \ \ = 1
