Section: Chapter 9, system of higher order odes
Problem number: 1919.
ODE order: 1.
ODE degree: 1.
The type(s) of ODE detected by this program : "system of linear ODEs" Unable to solve or complete the solution.
Solve \begin {align*} x^{\prime }\left (t \right )&=-x \left (t \right ) y \left (t \right )^{2}-x \left (t \right )^{3}+y \left (t \right )+x \left (t \right )\\ y^{\prime }\left (t \right )&=-x \left (t \right )^{2} y \left (t \right )-y \left (t \right )^{3}-x \left (t \right )+y \left (t \right ) \end {align*}
Does not currently support non linear system of equations. This is the phase plot of the system.
✗ Solution by Maple
