The direction fields of three DEs are shown in Fig. 2.2.3. (a) Label the equations linear or
Question:
(a) Label the equations linear or nonlinear. Of the two that are linear, which is homogeneous and which is non homogeneous?
(b) Explain (algebraically) why the sum of two solutions of a homogeneous linear DE is a solution. Verify that the negative of such a solution is also a solution, so y = 0 must be a-solution.
(c) Interpret the observations of pan (b) for the direction fields in Fig. 2.2.3. Visualize two solutions and then their sum. Does the sum follow the direction field?
