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.
