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 3D perspective  
Excel Surface Graphing Utility 
A downloadable Excel spreadsheet that lets you graph surfaces of the form z = f(x, y) in 3D perspective 

Regression Tools  
Simple Regression  Instantly gives you the equation of the line or exponential curve through two points, and also the bestfit (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 bestfit (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 GaussJordan Tool  Can be used for Gauss Jordan row reduction and the simplex method; works in fraction, integer, and decimal mode  
Excel Pivot and GaussJordan 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.  
4State 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 ongoing controversies.  
Popup Factorials, Permutations and Combinations Computer  This handy popup 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 leftsum 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).
