<p><span style="font-size: 24pt;"><strong>Trigonometry Derivative Rules</strong></span></p>
<p><span style="font-size: 18pt;">Trigonometry is the study of triangles and their properties.&nbsp;</span></p>
<p><span style="font-size: 18pt;">It has applications any time there is a need for a triangle, there is circular motion, or a regular repeating pattern.&nbsp;</span></p>

<p>Knowing these facts allows us to figure out the derivative rules for these functions.&nbsp;</p>

<p>You can do a process similar to the one above to come up with all of the trig derivative rules! But if you just want to memorize them, there's a nice way to do that.</p>
