<p>I just bought a TI 83 Plus calculator and have no clue what to do, i read the manual but didnt get much of it so i was hoping that someone would tell me what kinds of stuff do i need to know for the math ic test.
i would really appreciate the help :)
thanks</p>
<p>You don't REALLY need a graphing calculator, but useful things are the "solver" and how to graph. I can't really explain it over the net but hopefully someone can help you.</p>
<p>Oh wait...math IC. I'm not sure if these things still apply.</p>
<p>i never touched the directions, except for learning how to do martices which i have long forgotten.</p>
<p>Seriously just spend and hour playing around with it. It should help.</p>
<p>aha
can anyone tell me what to press type or whatever to find the intersection of a circle and a line ?
what to press to graph 2 circles at the same time?
what to press to find the x ( roots) of a function ??
( i got the calculator cos i really want to raise my score to a 700 at least)
thanks again</p>
<p>Borrow or buy the Barron's book for Math IIc. Inside you'll find a section with the most wonderful tips on using a graphic calculator that are relevant to this exam. I learned that I can do things on my ti-83 that I thought were only possible on a ti-89 (like solving geometric progressions).</p>
<p>Hope that will help you. </p>
<p>Also download and install a program called "Polysmlt" from the Ti website (if its not already installed on your calculator). It allows you to solve functions to the power of x even with non-real answers (you must be in "a+bi" mode on your calculator though--its set to "function" mode by default) and also solve simultaneous equations with multiple variables. I find this program is quicker than graphing the function to find the points of intersection.</p>
<p>@Strawberriice: in order to raise your score >> 700, the biggest step would be to avoid making careless errors, by constant practise (depriving yourself of as much comfort as possible, try no calc if you can.) and to get all your concepts down so that you don't omit questions. the GC may not be that large of a help, at least, having used a TI-89 for 2+ years, i'm still not sold.</p>
