<p>How does one do sec and/or sec^(-1) on the TI?</p>
<p>i know it is something to do with 1/cos, but can you include the exact parenthetic usage as well.</p>
<p>ty</p>
<p>u just type in Sec( … or go to the catalog and pres S (3) And it will be the first one there (Sec^(-1) is right under it)</p>
<p>Or go to 2nd, math (5), A: Trig.</p>
<p>catalog is faster though</p>
<p>Yeah, just providing an alternative.</p>
