   Derive, the successor to muMATH, is a computer-algebra system for all
   IBM-PC  and NEC PC-9801 compatible computers having at least 512K of
   RAM and MS-DOS 2.1 or later.  Interface novelties include:
   
   1.  A simple menu-driven interface.
   2.  Full utilization of the standard IBM-PC hardware.
   3.  An exceptionally lenient parser-scanner.
   4.  The ability to directly select subexpressions in previous inputs
       and results for selective simplification or composition.
   5.  A seamless symbolic-numeric interface.
   6.  A seamless symbolic-graphic interface.
   7.  A compact program.  Derive comes on a single standard 5.25 inch or
       3.5 inch diskette and requires no installation.  Although we 
       recommend making a working copy, Derive can be run directly off
       the distributed diskette.  Installation procedures that computer
       scientists regard as trivial can overwhelm computer novices who
       just want to insert one diskette then execute a program.  Moreover,
       Derive does not require a co-processor or a hard disk, and Derive
       runs even on the hand-held Poqet computer.  These features makes
       it very accessible to anyone with an inexpensive home or portable
       computer, yet they can run the same program on a 486-based speed
       demon wherever they have access to one.
   8.  Exact and approximate arithmetic to thousands of digits.
   9.  Equations, complex numbers, trigonometry, calculus, vectors, and
       matrices.
   10. 2D and 3D function plotting with zooming capability.
   11. CGA, EGA, VGA, and Hercules graphics support.
   12. Attractive 2D mathematical display of formulas.
   13. Easy to use menu-driven interface with on-line help. 
   14. Ideal for students, teachers, engineers and scientists.
