<h4 class="subsection">10.5.1 Introduction to Trigonometric</h4>
<p>Maxima has many trigonometric functions defined. Not all trigonometric
identities are programmed, but it is possible for the user to add many
of them using the pattern matching capabilities of the system. The
trigonometric functions defined in Maxima are: <code><a href="maxima_55.html#acos">acos</a></code>,
<code><a href="maxima_55.html#acosh">acosh</a></code>, <code><a href="maxima_55.html#acot">acot</a></code>, <code><a href="maxima_55.html#acoth">acoth</a></code>, <code><a href="maxima_55.html#acsc">acsc</a></code>,
<code><a href="maxima_55.html#acsch">acsch</a></code>, <code><a href="maxima_55.html#asec">asec</a></code>, <code><a href="maxima_55.html#asech">asech</a></code>, <code><a href="maxima_55.html#asin">asin</a></code>,
<code><a href="maxima_55.html#asinh">asinh</a></code>, <code><a href="maxima_55.html#atan">atan</a></code>, <code><a href="maxima_55.html#atanh">atanh</a></code>, <code><a href="maxima_55.html#cos">cos</a></code>,
<code><a href="maxima_55.html#cosh">cosh</a></code>, <code><a href="maxima_55.html#cot">cot</a></code>, <code><a href="maxima_55.html#coth">coth</a></code>, <code><a href="maxima_55.html#csc">csc</a></code>, <code><a href="maxima_55.html#csch">csch</a></code>,
<code><a href="maxima_55.html#sec">sec</a></code>, <code><a href="maxima_55.html#sech">sech</a></code>, <code><a href="maxima_55.html#sin">sin</a></code>, <code><a href="maxima_55.html#sinh">sinh</a></code>, <code><a href="maxima_55.html#tan">tan</a></code>,
and <code><a href="maxima_55.html#tanh">tanh</a></code>. There are a number of commands especially for
handling trigonometric functions, see <code><a href="maxima_57.html#trigexpand">trigexpand</a></code>,
<code><a href="maxima_57.html#trigreduce">trigreduce</a></code>, and the switch <code><a href="maxima_56.html#trigsign">trigsign</a></code>. Two share
packages extend the simplification rules built into Maxima,
<code><a href="maxima_58.html#ntrig">ntrig</a></code> and <code><a href="maxima_58.html#atrig1">atrig1</a></code>. Do <code>describe(<var>command</var>)</code>
for details.
