NAME

       rmath - a computer algebra system with functions and readline
       matho - a computer algebra system with functions

SYNOPSIS

       rmath [ input_files ]
       matho [ input_files ]

DESCRIPTION

       Mathomatic is a general-purpose computer algebra system (CAS) that can symbolically solve,
       simplify, combine, and compare algebraic  equations,  perform  standard,  complex  number,
       modular, and polynomial arithmetic, etc.  It does some calculus and handles all elementary
       algebra, except logarithms.  Plotting expressions with gnuplot is also supported.

       rmath and matho are shell scripts that allow you to use Mathomatic with input of functions
       like  sin(x) and sqrt(x) automatically expanded to equivalent algebraic expressions by the
       m4 macro preprocessor.  A matching pair of parentheses is required around  the  parameters
       for all functions in m4 Mathomatic; m4 requires this.  rmath also runs the rlwrap readline
       wrapper utility if available, to provide readline input editing support  similar  to  that
       provided by mathomatic(1).

       rmath  and  matho  define  and  enable named math functions in Mathomatic.  Most functions
       enabled here should be  real  number,  complex  number,  and  symbolically  capable.   One
       exception  is  the abs(x) function, which doesn't work with complex numbers, because it is
       defined in Mathomatic as (((x)^2)^.5).

       The following general functions are defined when using rmath or matho:  sqrt(x),  cbrt(x),
       exp(x),  pow(x,y),  abs(x), sgn(x), factorial(x), gamma(x), floor(x), ceil(x), int(x), and
       round(x).

       The following standard  trigonometric  functions  are  defined:  sin(x),  cos(x),  tan(x),
       cot(x),  sec(x),  and  csc(x).   sinc(x)  is  the  normalized  sinc  function,  defined as
       sin(pi*x)/(pi*x).

       The following standard hyperbolic trigonometric functions are defined:  sinh(x),  cosh(x),
       tanh(x), coth(x), sech(x), and csch(x).

       The  following  universal constants are defined: pi, e, i (the imaginary unit), euler (the
       Euler-Mascheroni constant), omega, and phi (the golden ratio).

GENERAL

       Text files may be specified on the shell command line that will be automatically  read  in
       through  the  m4  preprocessor  into  Mathomatic.  After any files are read in, Mathomatic
       prompts for input from the console.

       Mathomatic is best run from within a terminal emulator.  It uses console  line  input  and
       output  for the user interface.  First you type in your mathematical equations in standard
       algebraic notation, then you can solve them by typing in the variable name at the  prompt,
       or  perform  operations  on them with simple English commands.  Type "help" or "?" for the
       help command, "help examples" to get started.  If  the  command  name  is  longer  than  4
       letters,  you  only  need  to  type  in the first 4 letters.  Most commands operate on the
       current equation by default.

       Complete documentation is available in HTML and PDF formats; see the  local  documentation
       directory  or  online  at  "http://mathomatic.org/math/doc/"  for  the  latest  Mathomatic
       documentation.

FILES

       ~/.mathomaticrc
              Optional startup file containing Mathomatic set command options.  It  should  be  a
              text  file with one or more set options per line.  For example, the line "no color"
              will make Mathomatic default to non-color mode, which is useful if you aren't using
              a supported color device.
