Best ResponseYou've already chosen the best response.1It depends on the type of equation. There are lots of different ways to do it.

Best ResponseYou've already chosen the best response.0yes, i'm just trying to refresh my knowledge on it. Do you know of any good source where I can see some examples?

Best ResponseYou've already chosen the best response.1For Differential Equations after calculus or for derivatives?

Best ResponseYou've already chosen the best response.0well I guess it would be after calculus but this is the eqn \[dy/dt=5y^2+3uy+6u^2\]

Best ResponseYou've already chosen the best response.1There is no way to make that linear. It's a quadratic and polynomials of degrees other than one cannot be changed to become linear.

Best ResponseYou've already chosen the best response.1Also, are you sure all the variables are right? Because right now you have a diff.eq in which you're deriving with respect to a variable that isn't on the right side of your equation...

Best ResponseYou've already chosen the best response.0dy/dt? there are ys on the right side?

Best ResponseYou've already chosen the best response.1Yes but the equation is taking the derivative with respect to t. It would be the same as if I had equation y = x^2 + xy + y^2 and then took the derivative with respect to t I would get dy/dt = 0 because I have no variables with t in them, therefore everything else is considered a constant. Since you don't have t on the right side anymore, I'm assuming that the original equation was something like (−5y^2+3uy+6u^2)*t Otherwise, the right side would be dy/du

Best ResponseYou've already chosen the best response.0good catch but the question given has dy/dt though, i'm guessing prof made a mistake :)

Best ResponseYou've already chosen the best response.0sorry just realized both u and y are a function of t, should be y(t) and u(t)
