I´ve never studied anything about systems of differential equations, but I´ve came across with two I´ve got to solve, which are nonlinear.
AND
I´ve been looking on internet and I´ve foudn this method for linear SD: https://www.youtube.com/watch?v=2vB3fx5BImU
But my question is, if there is a numerical method or something with which i can "solve" this systems.
