|
|
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 |
|
Linear Programming Grapher |
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! |
| 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 5 5. |
|
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 | ||
| Monty Hall Simulation | This simulation of the game show should put to rest once and for all the on-going controversies. |
