Topics in a Differential Equations Course


To learn more about a topic listed below, click the topic name to go to the corresponding MathWorld classroom page.

Bessel Function of the First Kind A solution to a particular nonlinear second-order differential equation. Bessel functions appear in many physics applications when solving classical partial differential equations in cylindrical coordinates.
Differential Equation An equation that involves the derivatives of a function as well as the function itself.
Euler Forward Method An numerical method for solving ordinary differential equations.
Fourier Transform A generalization of complex Fourier series that expresses a function in terms of frequency components. Fourier transforms arise quite commonly not only in mathematics, but also in optics, signal processing, and many other areas of science and engineering.
Laplace Transform An integral transform perhaps second only to the Fourier transform in its utility in solving physical problems. The Laplace transform is particularly useful in solving linear ordinary differential equations such as those arising in the analysis of electronic circuits.
Ordinary Differential Equation An equality involving a function and its derivatives.
Partial Differential Equation An equation involving a function and its partial derivatives.
Second-Order Ordinary Differential Equation An ordinary differential equation that contains derivatives of second order but of no higher orders.
Separation of Variables A method of solving differential equations.
Slope Field A particular visualization of a linear, first-order differential equation in which the derivative at a given point is represented by a line segment of the corresponding slope.
