I can't do these diff. eqns.
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?
