In mathematics, an ordinary differential equation (ODE) is a differential equation containing one or more functions of one independent variable and the derivatives of those functions. The term ordinary is used in contrast with the term partial differential equation which may be with respect to more than one independent variable An ordinary differential equation (frequently called an ODE, diff eq, or diffy Q) is an equality involving a function and its derivatives.

Introduction. Recall, from your calculus class, that solving a system of ordinary differential equations (ODEs) $\frac{d}{dt}\mathbf{y}(t) = \mathbf{f}(\mathbf{y}(t))$ means finding a (vector-valued) function $$\mathbf{y}(t)$$ that satisfies the system of equations.

However, certain properties of such equations are more conveniently studied with the aid of complex numbers

Unlike most texts in differential equations, this textbook gives an early presentation of the Laplace transform, which is then used to motivate and develop many of the remaining differential equation concepts for which it is particularly well suited When a differential equation involves a single independent variable, we refer to the equation as an ordinary differential equation (ode). Example 1.0.2. If there are several dependent variables and a single independent variable, we might have equations such as dy dx = x2y xy2 +z, dz dx = z ycos x The laws of nature are expressed as differential equations.

Ordinary differential equations are much more understood and are easier to solve than partial differential equations, equations relating functions of more than one variable. We do not solve partial differential equations in this article because the methods for solving these types of equations are most often specific to the equation.
