I can't do these diff. eqns.

  1. Dec 14, 2003 #1
    I have been trying to solve the following differential equations I was stuck with them. I will appreciate any help from you;
    1- 3 y' +3x/y =2(xy)^4
    I have tried Bernoulli but I could not get a standard form.
    2- x' -2 x y = y exp (-3y^2)[x exp(-y^2)+ 3(x exp(-y^2))^2]
    I have tried here the substitution x exp(-y^2)= u , but I could not also find the solution.

    Can any one do it?
