1.) 3y' + 3xy = e^-3(x^2)/6
My result y=C*e^-3(x^2)/6 + x*e^-3(x^2)/6 but it's not correct.
2.) x^2 y'' - 3xy' + 3y = 0
I don't know how to solve this one
Does anyone know where can I find a website with solved differential equations step by step and good explanation?
How can I solve diff. equations with program Mathematica. I think I have to use DSolve but then I don't know the correct form (especialy how to type y' or y'')
