1 and classify all equilibrium points, draw a phase line, sketch solutions in the lane, and determine whether each equilibrium point is asymptotically stable, semi- le, or unstable.

Consider the autonomous equation: P = 0.05P(100 – P)-h, where P is an animal population, and h is the number of animals harvested per unit time. Determine the values of h which yield no equilibrium states, one equilibrium state, and two equilibrium states. (Your responses should involve equalities or inequalities involving h and a real number.) No equilibrium state: One semi-stable equilibrium state: Two distinct equilibrium states:

Find the general solution in terms of real functions. (b) From the roots of the characteristic equation, determine whether each critical point of the corresponding dynamical system is asymptotically stable, stable, or unstable, and classify it as to type. (c) Use the general solution obtained in part (a) to find a two-parameter family of trajectories x=x1i+x2j=yi+y′j of the corresponding dynamical system. Then sketch by hand, or use a computer, to draw a phase portrait, including any straight-line orbits, from this family of trajectories.

Find the steady-state, solution of the system in Fig. 70 when m = 4, c = 4, k = 17 and the driving force is 202 cos 3t.
