3.0 A better way to understand Differential Equations | Nonlinear Dynamics | Linearization
These second-order nonlinear differential equations can be written in the form: dx/dt = f(x,y) dy/dt = g(x,y) Got a nonlinear differential equation? No problem, just linearize it! This method approximates the vector field as a linear...

1.0 A better way to understand Differential Equations | Nonlinear Dynamics | 1D Linear Diff Eqns
Here we show another way to graphically interpret first order ordinary differential equations (ODE's) in the form dx/dt = f(x). Rather than solve the differential equation by integrating, which is often impractical, it's useful to graph...
