NetID: _ MATH 1106 - Prelim l - 03112/2019 Page 317 Question 3. Consider the populations of seals (S) and polar bears (B). The polar bears hunt and eat the seals. The equations describing the evolution of these two populations are: S 0 : 4S - 283 B0 = 3B + 3SB The goal of this exercise is to use Euler's method to approximate a trajectory. a) Suppose we start at t : 0 with 1 seal and 1 polar bear. Use Euler's method with a step size of At : 0.5 to estimate the populations at t = 1
