## Solution curves

Consider the fact that the solution curves of a first degree differential equation cannot cross (as at the point of a hypothetical crossing, they would have to have the same values of t and y but different y' values, and thus could not both be solutions to the same first order differential equation).

Now look at and in terms of your equation.
