Hi, I have to find the general solution to this second order pde.

Where x and y not equal to 0.

I have found characteristics to be n=xy and v=y/x and I have used these to change the variables to get

1/(2n)

And now i'm stuck, for some reason I just dont know how to solve this with the first order partial derivative on the RHS.

Please help.

Thanks Katy :)
