Systems of Differential Equations Part 2: Matrices and Stability
We just looked at some simple ways to solve systems of differential equations, via modeling and elimination. But there are other methods, some of which involve matrices. This will require that we remember some concepts from linear...

Nonlinear Systems 1
In this video, we use our background of solving linear systems to solve a nonlinear system.
Curated Video
Nonlinear Systems (2)
In this video we solve two systems of nonlinear equations. The first has an absolute value function and a circle (and we solve by graphing). The second has a linear function and a quadratic.

Khan Academy: Algebra: Conic Sections: Non Linear Systems of Equations 3
The final video in a series of lessons on solving non-linear systems of equations. A quadratic system is given and, in the process of solving algebraically, it is determined that there is no solution. This conclusion is confirmed...

Khan Academy: Algebra: Conic Sections: Non Linear Systems of Equations 2
The second in a series of video lessons on solving non-linear systems of equations. This video shows an example of how to solve a system in which both equations are quadratic by using the substitution method. After the solutions are...
