Analytic Solution for the Burgers Equation Provides the general analytic solution for the Burgers equation in the form of a 4-D commutative hypercomplex function. The solution exhibits the main dynamic features in a Burgers medium: propagation of disturbances, shock waves, propagating state change fronts, and solitons. A page is included to explain the hypercomplex mathematics. http://home.usit.net/~cmdaven/burgers.htm

Table of Laplace Transforms This page contains an extensive table of Laplace transforms. Laplace transforms are used to solve certain differential equations. http://www.vibrationdata.com/Laplace.htm

Difference Method for Numerical Approximation to Applied Differential Equations. This page explains how to use the difference formula of differentials to approximate the differential equations for applied systems. This method is used when analytical techniques are unavailable or cause computers to spit out garbage. This difference method is very similar to the Runge-Kata and Newton's method. http://www.geocities.com/b_ward.rm/na.html
