This is because trigonometry was initially used to study relationships between different sides of a given triangle. Applications of the material can be found, both historically and contemporarily, in many areas. Trigonometry can be applied in the fields of surveying, navigation, planetary motion, and vibrations (sound waves, guitar strings), to name a few. <P> <HR><center> <table border=1> <td><A HREF="node5.html"><img height=36 width=36 alt="PREVIOUS" src="/UCESIcons/tools/previous.gif"></A></td> <td><A HREF="node5.html"><img height=36 width=36 alt="UP" src="/UCESIcons/tools/up.gif"></A></td> <td><A HREF="node7.html"><img height=36 width=36 alt="NEXT" src="/UCESIcons/tools/next.gif"></A></td> <td><a href="contents-node6.html"><img height=36 width=36 alt="CONTENTS" src="/UCESIcons/tools/toc.gif"></a></td> </table> </center> <HR><P><ADDRESS> <I><A HREF="http://www.math.psu.edu/sellersj/">James A.
