Automatic optimal viewing window, displays asymptotes, discontinuities, piecewise graphing, etc. Also 'guess the graph', galleries, articles on graphing concepts and tricks. Very useful for high school students and teachers. www.webgraphing.com
Function Flyer
Creates graphs of functions but also allows the manipulation of constants and coefficients in any function so the user can explore the effects on the graph by changing those numbers. Great tool! Student would get more out of it if there was a guideline or lesson plan to follow in the explorations. www.shodor.org/interactivate/activities/flyall/index.html
The Function Institute from Zona Land Comprehensive discussion on definition of a function with Java applets that illustrate very clearly one-to-one, one-to-many, many-to-one concepts. Also has pages on different types of functions (linear, polynomial, rational, exponential, trigonometric) and interactive graphs of those. id.mind.net/~zona/mmts/functionInstitute/functionInstitute.html
Mathinsite Products
A collection of very instructive Java applets with tutorial
worksheets on graphing different functions (line, parabola, exponential
function, circle, ellipse, trig functions, complex numbers and more). mathinsite.bmth.ac.uk/html/applets.html
MathsNet Interactive Graphs
Get a clear and complete understanding of coordinates and graphs with this very comprehensive and extensive step-by-step tutorial. Every page is interactive, using either interactive geometry, graphing or algebra
applets. Includes how to plot graphs, all about the geometry of the straight line, tutorials for quadratic, cubic, and reciprocal curves, circles, solving, and more. www.mathsnet.net/graphs/index.html

computer. Make 2D and 3D graphs, different number bases, statistical analysis, calculus, etc. Price: Free www.graphcalc.com/
Calc98
Engineering, scientific and financial freeware calculator for
Windows. Functions for statistics, use of different number bases, metric units conversions and physical properties and constants. Also has financial and time functions including investment, loan and mortgage calculations, a stopwatch. Price: Free www.calculator.orgdownload.html
SpeQ Mathematics
Small but extensive math program for calculations and graphing. Can also define variables and save your calculations. Price: Free www.speqmath.com
SVGCalc
An open-source scientific graphing calculator for web browsers. It can be stored on a hard drive, accessed over a local or wide area network, or made available via an internet webpage. Provides calculation and graphing tools commonly needed by high school math and science students. Price: Free www.lakeland272.org/tlhs/csabatke/svgcalc/
A & G Grapher
A basic 2D/3D graphing program. Add tangent lines by clicking on the graph, trace the graph, calculate area. Also draws implicitly defined functions/graphs. Easy to learn. Price: A 10-day free trial. $19.95. www.runiter.org/grapher.htm
MathGV Function Plotting Freeware for Windows
Plot 2 dimensional, parametric, polar, and 3 dimensional functions. You can add lines, rectangles, circles, round rectangles, flood fills, and text for labels or for artistic effects. Because the plots are shown with a big screen, and are extremely easy to zoom in/out or move around, MathGV is excellent for visualizing graphs and functions in middle/high school. It does NOT have calculus or tracing tools. Price: Free www.mathgv.com
Mathscribe Lite 2.5.1
Mathscribe is a simple dynamic graphing and mathematical modeling program for algebra, trigonometry and precalculus classes. The free download includes 13 ready-to-print-n-use assignments, which I consider
a real benefit of this program. They cover linear equations, systems of linear equations, and quadratic equations. Also, the program comes with lots of pre-made examples of different kinds of functions for the high school algebra/pre-calculus student. You can also use Mathscribe to mathematically model scientific data, either by typing in the data from scratch, or simply pasting it from a spreadsheet or other program. Mathscribe lacks the zooming in/out and centering functions present in many plotting programs. Its strength is in the ready-made examples and lab sheets, helping the student to connect both symbolic and visual thinking through guided discovery. Price: Free www.mathscribe.com/
MathProf
A comprehensive program, like a math professor on your desktop. Not only for algebra, but for analysis, geometry, 3D figures, stochastics, vector algebra, and linear algebra.
Download is free. Price: $45. www.redusoft.org/
Graphmatica
Very easy to use, fast, compact graphing program. Plots 2D graphs,
implicitly defined functions, in polar coordinates, piecewise, parametric graphing. Finds derivative and area under curve. Use a parameter/free variable. Data plotting, curve fitting, differential equations. Recommended for middle school/high school algebra and calculus. Price: It's up to you what you pay; if you find Graphmatica easy, helpful, and convenient to use, you are asked to support the release of future versions by sending your contribution to the developer. www.graphmatica.com
Advanced Grapher
