BACKGROUND DESCRIPTION OF EXPLORE EXPLORE FEATURES EXPLORE CONVENTIONS SUPPORTED PLATFORMS DOWNLOAD PROGRA)M DEMONSTRTATION OF E(XPLORE)

David Meredith, of San FranciscoState University, had as his objective

being able to solve mathematicalformulas on a PC as they would be

conventionally written.

He achieved this objective in the 1990’s.

X(PLORE) program now available on line.

Evaluate formulas including derivatives

and integrals Graph functions in two and three variables Perform all common matrix operations Use the language of abstract linear algebra Write subroutines in a powerful mathematical

language

Comments are preceded by // Math functions:

Multiply *Divide /Add +Subtract -Calculus

Differentiate a = Dif ( f(x), x) Integrate a = In ( f(x), x =a to b)

Graph:2D - Graph(function1, x=1 to n)2D - Graph((function1,function2), x=1 to n)3D – Graph3D(function1, function2, x=-1 to 1, y=-1 to 1)
