Where ![\"\"](\"http://www.mathskey.com/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=fbb11e84b9051b939840bf4a8a6c208d.png\")
is amplitude and period ![\"\"](\"http://www.mathskey.com/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=127cc575e0ec6139a519f55b564f68be.png\")
.
Compare the function with general form of sine function.
\Here amplitude is ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=36a3760a97bb7e148c60581fa6d9fa8c.png\")

The period is ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=ebdc8da154e3a9bda87fd794a6155619.png\")
.
Therefore, the sine wave starts with an amplitude of ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=d9285d5a293c4e12028128b0fb74ba46.png\")
units at ![\"\"](\"http://www.mathskey.com/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=186bbab1ce15e0a036879b2e2b51fb93.png\")
and completes one cycle at ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=99dde57526f34f642b9249d093738433.png\")
