Ordinary Differential Equations

Definition

An ordinary differential equation (ODE) is an equation that contains one or several derivatives of an unknown function, which we usually call y(x) (or sometimes y(t) if the independent variable is time t ). y’ means dy/dx (or the first derivative of y y’’ means d^2 y/dx^2 or the second derivative of y y’’’ means d 3 y/dx 3 or the third derivative of y
