While Mathematica is an infinitely extensible programmable tool, many of the functions that engineers need on a day-to-day basis are just a few keystrokes away. Here are a ...

In this demo, we consider a f(t) = A*cos(2*Pi*ft+Theta) and draw its time domain plot and frequency domain plot, i.e., magnitude and phase spectrum and demonstrate the ...

A basic Mathematica notebook illustrating a wide range of graphics and sound functions.

This package incorporates a few commands for representing space curves in color.

This notebook illustrates how to construct contour lines on a saddle plotted using ParametricPlot3D.

The package Riemann.m provides three commands: PlotRiemann, RiemannSum and RiemannSumList. PlotRiemann[expression, range, {plotoptions}, {riemannoptions}] produces a plot of ...

DiffEqs is a collection of fast, robust, and thoroughly tested packages for differential equations. The primary package in DiffEqs is DEGraphics, which provides the ...
