Best ResponseYou've already chosen the best response.2If dy/dx = 2x, what is the general solution of that equation? It's y(x) = x^2 + C. Now is there ANY choice of the number C such that y(0) = 0 and y(1) = 100?

Best ResponseYou've already chosen the best response.0Ya general solution y=x^2 + c1 no problem. but the book says "Show that the problem has no solution. Is this an Initial value problem?" I don't how this statement can be correct when c can take on any value since it is arbitrary.

Best ResponseYou've already chosen the best response.0right you have a contradiction so there is no y with those conditions that satisfy the differential equation

Best ResponseYou've already chosen the best response.2Given that y(x) = x^2 + c, you now what to find ONE value of c such that it both true that y(0) = 0 AND y(1) = 100 Does there exist one value of c such that both of those conditions are satisfied?

Best ResponseYou've already chosen the best response.2Therefore the initial value problem y' = 2x, y(0) = 0, y(1) = 100 has no solution.

Best ResponseYou've already chosen the best response.0why does it have to be so opaque, but yet so simple.

Best ResponseYou've already chosen the best response.2it's not opaque now. That's why we do exercises! :)
