Hi there, I have a question on differential equations I dont understand, here it is:

find the general solution:

t (dx/dt) = x + (sin(x/t))^2

I think you have to use substitution for this one but dont know how, any ideas?

Define . Then . Now, our original equation tells us , and so:

Which you should be able to solve for u(t). Then just use x=ut to find x.
