Section: Chapter 9, system of higher order odes
Problem number: 1915.
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 )^{2} a p +x \left (t \right ) y \left (t \right ) a q +x \left (t \right ) \alpha \\ y^{\prime }\left (t \right )&=x \left (t \right ) y \left (t \right ) b p +y \left (t \right )^{2} b q +y \left (t \right ) \beta \end {align*}

Does not currently support non linear system of equations. This is the phase plot of the system.

Solution by Maple

dsolve([diff(x(t),t)=x(t)*(a*(p*x(t)+q*y(t))+alpha),diff(y(t),t)=y(t)*(beta+b*(p*x(t)+q*y(t)))],singsol=all)
