ASP, anAlgebraic ScratchPad, is Microsoft
Windows^{®} software
designed as a twodimensional graphic aid for mathematical and engineering applications. Its
unique expression evaluator allows for the graphing on the xy plane of individual
points and/or functions of a single variable, which are typed by the user in
standard algebraic form. ASP's
extremely simple Windows^{®} interface also makes it an axcellent educational
tool for both teacher and student (College Algebra and Calculus).
Its most recently incorporated feature ("MAT"), is a matrix algebra
tool with a highly malleable interface and millisecond expression evaluation. As a teaching
tool is features step by step animation for complex matrix operations. Written
originally for ITV use, has also become inclassroom choice with LCD projector.
ASP minimum hardware requirements are:
 Windows XP®, 98®, 95® or NT, 4MB of RAM, pentium75 processor, 0.5 MB
of disk space, 1024x768x256
color graphic/screen resolution.The program is distributed on a 3.5"
diskette. The installation is very simple and is handled entirely by the
installer utility which comes with the distribution. The installer creates a
desktop group and icon to facilitate later use of the program.
ASP's main features:
 Extremely simple and user friendly point and click interface.
 Fast graphing of individual data points and mathematical functions.
 Simultaneous display of up to 10 functions.
 Keeps a history list of all expressions entered during the session to facilitate later retrieval, reuse and reeditting.
 Allows for segmented and/or limited domain functions.
 Selectable font sizes, colors and trace widths to optimize presentations.
 Numerical evaluation and graphing of derivatives (point and click).
 Numerical evaluation and graphing of inverse of functions (point and click).
 Numerical evaluation of definite integrals.
 Zooming of user selected (cursor dragging) regions of the screen.
 Language option setting (English or Spanish) of the control panel.
 User selectable x and y ranges.
 Point and click printing of the screen.
 Cut and paste into the clipboard of user selected screen regions.
MAT's main features:
 Independent and point and click selectable row and column operations.
 Supports symbolic and/or actual numerical evaluation of
arbitrarily complex matrix expressions.
 User generated matrix archive.
