<p>Ok…before everyone posts that it is opp/hyp let me refine my question. I need to know the formula/equation that a calculator or anything goes through to compute sin. I am specifically lookin to see if this formula uses Pi in it. Does anyne know the formula for cos/tan? Any links would be appreciated.</p>

<p>I think that calculators use the CORDIC algorithm, <a href=“http://www.dspguru.com/info/faqs/cordic.htm[/url]”>http://www.dspguru.com/info/faqs/cordic.htm&lt;/a&gt;.&lt;/p&gt;
