ASP, anAlgebraic ScratchPad, is Microsoft
Windows® software
designed as a two-dimensional graphic aid for mathematical and engineering applications. Its
unique expression evaluator allows for the graphing on the x-y 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 in-classroom choice with LCD projector.
ASP minimum hardware requirements are:
- Windows XP®, 98®, 95® or NT, 4MB of RAM, pentium-75 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 re-editting.
- 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.
- Inverse of a square matrix.
- Matrix determinant calculation.
- Fast on-screen point and click editing of matrix elements.
- Operations among matrices.
- Matrix diagonalization in one step or by animated step by step tutorial.
- Operations with augmented matrices.
- Simplex Method in one step or by animated step by step tutorial.
- Selectable color and font sizes.
- Zooming of user selected (cursor dragging) regions of the screen.
