Best ResponseYou've already chosen the best response.0You know you have to solve it for y(x) if you can, of course  you could apply the initial conditions just now and solve for the constant. But I strongly recommend you to get the equation in explicit form if possible.

Best ResponseYou've already chosen the best response.0Almost, try again. You should end up with: \[\Large y(x)=6Ce^{\frac{1}{3}x^3} \] As you can see, I said above that \(y(x) \neq 6\) which was important, otherwise I would have divided the differential equation through 0. This equation supports that statement, this equation only becomes 6 in the limit as x approaches infinity.

Best ResponseYou've already chosen the best response.0Consider this equation: \[\Large e^{\ln2} = 2 \] but: \[\Large e^{\ln2} = 2 ????? \] Rather view it like that: \[\Large e^{\ln2}=\left(e^{\ln2}\right)^{1}=\frac{1}{2} \]

Best ResponseYou've already chosen the best response.0and then you should get the same expression as I do.
