WebNov 10, 2024 · The differential equation has a family of solutions, and the initial condition determines the value of C. The family of solutions to the differential equation in Example 9.1.4 is given by y = 2e − 2t + Cet. This family of solutions is shown in Figure 9.1.2, with the particular solution y = 2e − 2t + et labeled. WebThe original equation (3xy + y²) + (x² + xy) y' = 0, turns into (-3x² + x²) + (x² - x²) y' = 0, that is, -2x² = 0, or simplified x = 0. That is, x = 0 (the vertical Y-axis) is in fact a solution of our differential equation. But is this solution already included in our Ѱ (x,y) = C equation, that is, is x = 0 a solution for it?
