Suppose that a population of hacteria grows according to the logistic differential equation dP =0.01P-0.0002P2 dt where Pis the population measured in thousands and t is time measured in days. Logistic growth differential equations are often quite difficult to solve. Instead, you will analyze its direction field to acquire infom ation about the solutions to this differential equation. a) Calculate the maximum population M that the sumounding environment can austain. (Note this is also calked the "canying capacity"). Hint: Rewrite...

Ordinary Differential Equations (a) Write a Python function implementing the 4'th order Runge-Kutta method. (b) Solve the following amusing variation on a pendulum problem using your routine. A pendulum is suspended from a sliding collar as shown in the diagram below. The system is at rest when an oscillating motion y(t) = Y sin (omega t) is imposed on the collar, starting at t = 0. The differential equation that describes the pendulum motion is given by: d^2 theta/dt^2 =...
