ahh! i dont know how to use my calculator!

<p>yea so i've never used a graphing calculator in my life and i just borrowed one from a teacher today, and it is freaking complicated! i think i can figure most of it out, but does anybody know how i can program formulas into it so i dont have to memorize them? like the ones for spheres and cones and stuff. by the way, it's a TI-83 plus.</p>

<p>You can download programs with formulas at <a href="http://www.ticalc.org%5B/url%5D"&gt;www.ticalc.org&lt;/a>. </p>

<p>However, you may want to consider using a calculator you're more familiar with. Yes, its nice to have the functions of the 83+, but if you don't know how to use it quickly, you may end up wasting time.</p>

<p>I am taking the Math IIC test tomorrow and was wondering if I could bring two calculators to the test site and use them simultaneously. I have some very useful SAT II Math programs on my TI-83 Plus but feel much more comfortable with my plain old Casio. Is it permitted to use them TOGETHER on the test?</p>

<p>I highly doubt it. Check the Collegeboard website. One calculator website is: <a href="http://www.collegeboard.com/student/testing/sat/testday/calc.html%5B/url%5D"&gt;http://www.collegeboard.com/student/testing/sat/testday/calc.html&lt;/a>. I know you're allowed to bring backup calculators, but I really doubt a proctor is going to let you use two at the same time.</p>
