Let S and I satisfy the differential equations in 1. Assume I = 0. (a) If dI/dt = 0, find S. (b) Show that I increases if S is greater than the value you found in part (a). Show that I decreases if S is less than the value you found in part (a). (c) Explain how you know that your answer to part (a) is the threshold value.
