• linear or non-linear equations: Let y(t) be the unknown. Then, a 0(t)y(n) +a 1(t)y(n−1) +···+a n(t)y = g(t), (∗) is a linear equations. If the equation can not be written as (∗), the it’s non-linear. Two things you must know: identify the linearity and order of an equation. Example 1. Let y(t) be the unknown. Identify the order and linearity of

A differential equation, shortly DE, is a relationship between a finite set of functions and its derivatives. Depending upon the domain of the functions involved we have ordinary differ-ential equations, or shortly ODE, when only one variable appears (as in equations (1.1)-(1.6)) or partial differential equations, shortly PDE, (as in (1.7)).

terminology ‘differential equation’ in place of ‘ordinary differential equation’ at times. Also we use the abbreviation ODE which stands for Ordinary Differential Equation(s). Wherever convenient, we use the notation prime 0 to denote a derivative w.r.t. independent variable x; for example, y0 is used to denote y(1)). 2.

Note that this model is the same as the Exponential growth model if β = ∞ In the next two lectures we consider the case where foxes are introduced to the model This model is called a predator-prey system, and is similar to models describing populations of fish (prey) and sharks (predators) Systems of Ordinary Differential Equations – p.2/44

This concept is usually called a classical solution of a differential equation. The domain for ODE is usually an interval or a union of intervals.

the differential equation d dt P(t)=kP(t) is homogeneous. A solution of an ordinary differential equation is a function which satisfies the equation at all points in the domain of the function. Exercise 1–2. Show that the function P(t)=ekt solves the differential equation above. (Note that the domain of the function ekt is all real numbers t.) Are there
