  mathomatic - a computer algebra system
  mathomatic [ -bcdehqrtuvwx
  ] [ -s level ] [ -m number ] [ input_files or input
  ]
  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. Trigonometry and function expansion are
  supported in a separate program called rmath(1) . Plotting expressions with
  gnuplot is also supported.
  mathomatic is the main Mathomatic application that does
  interactive symbolic-numeric mathematics through a simple
  command-line interface. Readline support is usually compiled into
  this application, making it easy to edit input and recall
  previous input with the cursor keys. The numeric arithmetic is
  double precision floating point with about 14 decimal digits
  accuracy. Many results will be exact, because symbolic math is an
  exact math, and because multiple floating point numbers can be
  combined for a single mathematical value; for example:
  2^(1/3), which is the cube root of 2 exactly.
  
  
    - -b
- Enable bold colors. Color mode will be turned on and colors
    will be brighter if this option is specified. Same as the "set
    bold color" command.
- -c
- Toggle color mode. This mode outputs ANSI terminal escape
    sequences to make each level of parentheses a different color,
    for easier reading. Requires a terminal emulator that supports
    ANSI color escape sequences. If the colors are too hard to see,
    use the -b option to increase the color brightness.
- -d
- Set demo mode. Currently this mode only bypasses loading
    the startup (rc) file, and ignores the pause command. It also
    allows using the calculate command without prompting for the
    values of any of the variables.
- -e
- Process mathematical expressions and Mathomatic commands
    instead of input files on the shell command line, and then
    quit. Unquoted space characters are the line separators on the
    Mathomatic input that follows this option. Works similar to
    entering it into the Mathomatic main prompt, except the
    autoselect option is turned off. Useful for quick command-line
    calculations. The startup messages are not displayed with this
    option. Follow this option with "--" so that expressions can
    start with a minus sign (-).
- -h
- Display a brief help message listing all of these options
    and then exit.
- -m number
- Change the memory size of equation spaces. It is followed
    by a decimal, floating point number which is a multiplier of
    the default equation space size. This allows larger equation
    spaces so that manipulating extremely large expressions will
    succeed without getting the "Expression too large" error.
    Specifying a number higher than 100 may make Mathomatic
    unresponsive.
- -q
- Set quiet mode. The startup messages and prompts are not
    displayed. This is useful when piping or redirecting input into
    Mathomatic, because the input won’t be displayed, so
    prompt output should be turned off. This option does the same
    thing as the "set no prompt" command.
- -r
- Disable readline input processing. Readline allows line
    input editing using the cursor keys, and outputs terminal
    control codes, all of which can be turned off with this
    option.
- -s level
- Set the enforced security level for the Mathomatic session.
    Level 0 is the default with no security. Level 1 disallows
    shelling out (forking). Level 2 disallows shelling out and
    writing files. Level 3 disallows shelling out and
    reading/writing files. Level 4 is the highest security level
    and is the same as compiling with the -DSECURE option. This
    run-time option was created for use on open public
    servers.
- -t
- Set test mode. Used when testing and comparing output.
    Bypasses loading startup (rc) file, turns off color mode and
    readline, sets wide output mode, ignores the pause command,
    etc. It also allows using the calculate command without
    prompting for the values of any of the variables.
- -u
- Guarantee that standard output and standard error output
    are unbuffered. Also echoes all line input if not in quiet mode
    ( -q option ). Useful when piping.
- -v
- Display version number, then exit successfully.
- -w
- Set wide output mode for an unlimited width output device
    like the "set wide" command does. Sets infinite screen columns
    and rows so that 2D (two-dimensional) expression output will
    always succeed and not be downgraded to 1D output when it
    doesn’t fit in the display area. Use when redirecting
    output or with a terminal emulator that doesn’t wrap
    lines. This mode only affects 2D output.
- -x
- Enable HTML output mode (which is also valid XHTML). This
    makes Mathomatic output suitable for inclusion in a web page.
    Color and bold mode affect this mode, allowing HTML color
    output. Wide output mode is also set by this option, meaning
    expressions will always be displayed in 2D.
After
  any options, text files may be specified on the shell command
  line that will be automatically read in with the read command,
  unless the -e option is specified.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.
  A command preceded by an exclamation point (such as "!ls") is
  taken to be a shell command and is passed unchanged to the shell
  (/bin/sh). "!" by itself invokes the default shell, which is
  specified in the SHELL environment variable. "!" is also the
  factorial operator.
  Complete documentation is available in HTML and PDF formats;
  see the local documentation directory or online at "http://mathomatic.org/math/doc/

    - EDITOR
- The EDITOR environment variable specifies which text editor
    to use for the edit command.
    - ~/.mathomaticrc
- Optional startup file containing Mathomatic set command
    options. It should be a text file with one set option per line.
    Do not include the word "set". For example, the line "no color"
    will make Mathomatic default to non-color mode, which is useful
    if you aren’t using a standard ANSI terminal
    emulator.
Mathomatic has been written by George
  Gesslein II (gesslein@mathomatic.org), with help from the
  Internet community.
  The command to take the limit of an expression is
  partially functional and experimental. All else should work
  perfectly; if not, please report it as a bug to the author or on
  the Launchpad website: "https://launchpad.net/mathomatic
