<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> or <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,y),</i> <b>abs</b><i>(x),</i> <b>sgn</b><i>(x),</i> <b>gamma</b><i>(x),</i> <b>floor</b><i>(x),</i> <b>ceil</b><i>(x),</i> <b>int</b><i>(x),</i>
and <b>round</b><i>(x).</i>
<p> The following standard 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 named binary operators are defined:
<b>mod</b> for modulus.
<p> The following universal constants are defined: <i>pi,</i> <i>e,</i>
<i>i</i> (the imaginary unit), <i>euler,</i> <i>omega,</i> and <i>phi</i> (the golden ratio).

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 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. 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.

<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.
