An astonishing innovation in the teaching of calculus is the use of the race track principle. This little-known principle is elegantly used in the Calculus and Mathematica ...

Mathematica 4.1 extends the technologies and advances pioneered by Wolfram Research, Inc. in Mathematica 4. Enhaneed solvers, functions and an improved pattern matcher and ...

The simple pendulum problem in mechanics can be solved using the Sn Jacobi Elliptic function. In this notebook we make some nice plots of the phase space of the system using ...

PolarDensity.m is a package that provides two functions: PolarDensityPlot and ListPolarDensityPlot, which are analogous to the built-in DensityPlot and ListDensityPlot. ...

The package provides a simple implementation of quantile regression (a straightforward extension of median regression) as proposed by Koenker and Basset (1987). The ...

MathAutomator is a plugin for Apple's Automator application that comes with Mac OS X 10.4 Tiger. It can be used to evaluate text as a Mathematica (InputForm) expression. It ...

How can the optimum shape of a lens be found? To do this a lens is built by prisms, with each prism having the height h and the widths d-i on the top and d-i+1 at the base. ...

We present a web-project based on webMathematica that allows any internet user to depict spectra and bifurcation diagrams of several predefined types of boundary value ...

This talk will highlight the key role played by Mathematica in recently developed results on projectile motion with linear resistance. These include several new formulas ...

The tools of lattice theory are applied to readdress the static state feedback linearization problem for discrete-time nonlinear control systems. Unlike the earlier results ...
