10. Consider the differential equation dy/dt = 2√yl. (a) Show that the function y(t) = 0 for all t is an equilibrium solution. (b) Find all solutions. [Hint: Consider the cases y > 0 and y < 0 separately. Then you need to define the solutions using language like "y(t) = ... when t ≤0 and y(t) = ... when t > 0."] (c) Why doesn't this differential equation contradict the Uniqueness Theorem?
