<p>For anyone that has taken SAT II math iic....I'm studying for it right now, and do u really have to know all those long and complicated formulas (addition and subtraction for sin/cos, half-angle formulas, demoivres theorem, the like)? If so, I will be unhappy.</p>

<p>They didn't pop up on my (Oct) test, but it couldn't hurt to stick them in your calculator.</p>

<p>There are really good programs for the Math IIC at <a href="http://www.ticalc.org%5B/url%5D">www.ticalc.org</a>. They have all the trig formulas in a really nice format and you can just download them into your calculator in case you need them on test day.</p>

<p>thanks so much.</p>

<p>I went on the website and have found formulas I need, but now I have no idea how to download these into my calculator....</p>

<p>I know this is dumb, but how do i do this? Where in the computer do I plug in the wire thing? I'm stupid with computers..</p>

<p>do u have to buy a special plug?</p>

<p>There should be a little circular jack on the outside of your calculator. Connect the cord from there to a USB port (a skinny rectangular one) somewhere on your computer (on my laptop, its on the back).</p>

<p>I have a TI-83+ (won it in a competition, heh) which came with a cable to connect it to a computer, but I couldn't find a port in my computer that fit it. It wasn't a USB cable by the way.</p>

<p>I guess that's the advantage of taking A level math (and further math, which I'm taking) - we have to learn how to use all these formulae, but many of the more complicated ones are given in a formula list (we still have to memorize simple identities etc.).</p>

<p>I would say know the law of sines, and law of cosines (which might help with vector problems), many of the formulas needed are given to you at the beginning</p>

<p>HAHAHAHA, no u don't need any of that... it's pretty straight forward if u ask me...</p>

<p>I don't know; i had to use them for a few, unless there was another way to solve the problem that I'm not aware about</p>

<p>ahh, the beloved law of sines. its actually really easy to remember anyway. its the damn law of cosines thats sooo long!</p>
