The only thing I hadn't tried :D Thanks a lot :D

Homework Statement Hello everybody :) Now, I have a differential equation to solve. Its a Bernoulli's type of eq. Homework Equations (2x2lny-x)y' = y The Attempt at a Solution I tried of putting it in this way: y'/y = 1/2x2lny-x and then considerin z=1/y, but it doesn't seem...

Thank you everyone :)

Two functions? Yes, but can the whole equation be plotted using the sepparate functions? I am sorry, but I really need to imagine the area of integration. And as for the change of variables, I was thinking u = x^2 + y^2, ok, but then?

It doesn't seem to solve that way. Can you please write just the polar equation in this case?

"Hey guys, how are you? I was studying for my calculus final and stumbled upon a peculiar function. Homework Statement Now I have to find the area bounded by the function (x^2+y^2)^3=xy^4 using a double integral. Now, the problem is that the graph is totally unknown to me (I have some...
