I See Graphs 3.3

I See Graphs 3.3 is designed by a high school math teacher of 30 years as a useful tool which makes it possible for students to "see" abstract algebraic concepts. It's uniqueness and strength lie in the way it marries algebra and geometry in that way. Several features of the program cannot be found anywhere else in one package, if at all.

Among the unique characteristics of this software are the ability to graph implicitly-defined equations and non-functions, graph solutions to systems of inequalities in traditional and reversed form, and the ability to display free-form slider graphs with as many as four parameters. Teachers can use the program for classroom demonstrations, for creating worksheets and/or tests, and as the medium to collect and evaluate student performance.

In addition to the program, users can download lessons and worksheets that are classroom ready. The software covers topics from Algebra I, Algebra II, Trigonometry, Statistics, and Pre-Calculus.

Major Features:

1. it graphs 2D, 3D, polar and parametric equations
2. polar and parametric equations have a "lightning bug" that dynamically traces the graphs
3. it graphs implicitly-defined equations
4. it graphs equations that are not functions
5. it draws slider graphs that can leave shadows for easier interpretation
6. it draws slider graphs for virtually any function with as many as 4 parameters that can be adjusted with sliders
7. trig function graphs can have the x-axis marked in terms of π
8. the inverse of any equation can be graphed with one button-click
9. graphs can be captured to the clipboard or to disk for use in demonstrations, tests, etc.
10. functions:  practice graphing variations of y = f(x)
11. functions:  practice giving, in function notation, the equation of one graph in terms of a function whose graph is displayed
12. functions:  practice giving the actual equation of a graph
13. functions:  capture student work for evaluation
14. regression equations -- including equations for data that includes negative abscissas and/or ordinates
15. visual construction of data with a mouse
16. descriptive statistics associated with single lists and lists of ordered pairs
17. statistical hypothesis testing (µ, σ2, and ρ)
18. actual (not general) display of distribution functions
19. P-value representations
20. random number generator for several types of discrete and continuous random variables
21. reverse lookup for probabilities of several distribution functions
22. random number replication so all students can analyze the same data
23. vectors:  addition demonstrated with animation
24. vectors:  sums and/or cross-products calculated and displayed
25. vectors:  rotation in 3D to get the full perspective
26. matrices:  transpose, inverse, determinant, sum (when appropriate)
27. matrices:  generate systems of equations (consistent-independent, consistent-dependent, inconsistent)
28. matrices:  generate determinants for homework, tests, etc.
29. matrices:  practice with elementary row operations, including capturing work for evaluation
30. it is customizable:  you can use your school's mascot and/or school colors
31. 20 step-by-step tutorial activities about using the program can be downloaded
32. dozens of complete lesson plans can be downloaded
33. lesson plans are included in Help, so you can search for just the right plan
34. it's free!
