The most common classification of differential equations is based on order. The order of a differential equation simply is the order of its highest derivative. You can have first-, second-, and higher-order differential equations. First–order differential equations involve derivatives of the first order, such as in this example:

Differential Equation Modelling Differential equations provide an excellent way to model the changing dynamics of the real world. The solutions to these differential equations can then provide huge insight into the situation being modelled. Example 4: A doctor gives a patient 270mg of drug 𝑋. After 2 weeks the patient takes a blood test and ...
Stability Equilibrium solutions can be classified into 3 categories: - Unstable: solutions run away with any small change to the initial conditions. - Stable: any small perturbation leads the solutions back to that solution. - Semi-stable: a small perturbation is stable on one side and unstable on the other. Linear first-order ODE technique. Standard form The standard form of a first-order ...
