Graphers
Function Evaluator & Grapher Creates a table of values and graph for any function you specify
Excel Grapher A downloadable Excel spreadsheet that automatically graphs any function you enter -- just enter a formula and specify a range.
Excel First and Second Derivative Graphing Utility A downloadable Excel spreadsheet that automatically graphs any function you enter as well as its first and second derivatives.
Surface Graphing Utility A utility that lets you graph surfaces (explicit & parametric) in 3-D perspective

Excel Surface Graphing Utility

A downloadable Excel spreadsheet that lets you graph surfaces of the form z = f(x, y) in 3-D perspective
 
Regression Tools
Simple Regression Instantly gives you the equation of the line or exponential curve through two points, and also the best-fit (regression) line, polynomial and exponential curve using up to 16 data points (10 digit accuracy). Graphs it too. (Yes, we got Javascript to draw graphs!)
Multiple Linear Regression Instantly gives you the best-fit (regression) linear function of up to 4 independent variables and up to 16 data points. (10 digit accuracy)
 
Matrix and Linear Algebra Tools
Pivot and Gauss-Jordan Tool Can be used for Gauss Jordan row reduction and the simplex method; works in fraction, integer, and decimal mode
Excel Pivot and Gauss-Jordan Tool
A downloadable Excel spreadsheet version of the above utility. Also works in fraction, integer, and decimal mode

Type in any linear programming problem in two variables and press "Graph." Shows the feasible region, corner points, and optimal solution.
Simplex Method Tool Just type in any linear programming problem and press "Solve." Check your simplex method homework in a snap!
NEW!
Diet Problem Solver
Choose your foods you like, choose your objective and constraints, and press "Solve."
UPDATED!
Matrix Algebra Tool
Does symbolic computations with matrices. Check your matrix algebra homework!
Game Theory Tool Reduces by dominance, finds saddle points, and solves any game up to 55.
4-State Markov System Simulation Enter your own 4 4 (or smaller) transition probability matrix and watch the system move from state to state.
Markov Computation Utility Calculates powers of the transition matrix and its action on a distribution vector.
 
Probability and Statistics Tools
Steve Costenoble's Monty Hall Simulation This simulation of the game show should put to rest once and for all the on-going controversies.
Pop-up Factorials, Permutations and Combinations Computer This handy pop-up window allows you to compute factorials, permutations, and combinations.
Histogram Utility Gives the probability distribution, histogram, expected value and standard deviation for statistical data
Binomial Distribution Utility (Bernoulli Trials) Gives you the probability distribution and graph for binomial variables.
Normal Distribution Utility Computes areas under the normal curve to 10 digit accuracy.
 
Calculus Tools
Radically Updated! Numerical Integration Utility and Grapher Computes left and right Riemann sums, and trapezoid and Simpson's rule sums with graphical display of results. Also computes definite integrals numerically to the accuracy you specify using an adaptive quadrature algorithm.
Excel First and Second Derivative Graphing Utility A downloadable Excel spreadsheet that automatically graphs any function you enter as well as its first and second derivatives.
Riemann Sum Grapher A downloadable Excel spreadsheet that shows a graph along with the area corresponding to the left-sum approximation of the integral.
Two Dimensional Differential Equation Solver and Grapher Numerically solves and graphs two dimensional systems of first order differential equations (or single second order differential equations).
David Scherfgen's derivative calculator Not part of this site, but it does derivatives very nicely
David Scherfgen's integral calculator Not part of this site, but a very powerful utility that does integrals.
 
Math of Finance Tools
A utility to compute payments, etc. for annuities and mortgages
 
Miscellaneous
NEW!
Technology formula practice
This pop-up window shows you the mathematical equivalent of the technology formula you enter. Handy to check whether you have your parentheses in the right places!
