<h2><a name='sect2' href='#toc2'>Description</a></h2>
Mathomatic is a general-purpose computer
algebra system (CAS) that can symbolically solve, simplify, combine, and
compare algebraic equations, perform complex number and polynomial arithmetic,
etc. It does some calculus and handles all elementary algebra, except logarithms.
Plotting expressions with <a href='gnuplot.1.html'><b>gnuplot</b>(1)</a>
is also supported.
<p> <b>rmath</b> and <b>matho</b>
are shell scripts that allow you to use Mathomatic with input of functions
like <b>sin</b><i>(x)</i> and <b>sqrt</b><i>(x)</i> automatically expanded to equivalent algebraic
expressions by the <a href='m4.1.html'><b>m4</b>(1)</a>
macro preprocessor. Additionally, <b>rmath</b> runs the
<a href='rlwrap.1.html'><b>rlwrap</b>(1)</a>
program to provide readline input editing support.
<p> The following
general functions are defined when using <b>rmath</b> and <b>matho:</b> <b>sqrt</b><i>(x),</i> <b>cbrt</b><i>(x),</i>
<b>exp</b><i>(x),</i> <b>pow</b><i>(x),</i> <b>abs</b><i>(x),</i> <b>gamma</b><i>(x),</i> <b>mod</b><i>(x),</i> <b>floor</b><i>(x),</i> <b>ceil</b><i>(x),</i> and <b>int</b><i>(x).</i>
<p> The following trigonometric functions are defined: <b>sin</b><i>(x),</i> <b>cos</b><i>(x),</i> <b>tan</b><i>(x),</i>
<b>cot</b><i>(x),</i> <b>sec</b><i>(x),</i> and <b>csc</b><i>(x).</i>
<p> The following hyperbolic trigonometric functions
are defined: <b>sinh</b><i>(x),</i> <b>cosh</b><i>(x),</i> <b>tanh</b><i>(x),</i> <b>coth</b><i>(x),</i> <b>sech</b><i>(x),</i> and <b>csch</b><i>(x).</i>
<p>
The following universal constants are defined: <i>pi,</i> <i>e,</i> <i>i,</i> and <i>phi,</i> which
is the golden ratio.

<h2><a name='sect3' href='#toc3'>General</a></h2>
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.
<p> 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 infix 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.
If the command is longer than 4 letters, you only need to type in the first
4 letters. Most commands operate on the current equation by default.
<p> Complete
documentation is available in HTML and PDF formats; see the local documentation
directory or online at "<a href='http://mathomatic.org/math/doc/'>http://mathomatic.org/math/doc/</a>
" for the latest
Mathomatic documentation.

<h2><a name='sect4' href='#toc4'>Files</a></h2>
<dl>
<dt><b>~/.mathomaticrc</b> </dt>
<dd>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. "rc" stands for "run cold".
