<p>I have a TI-84 Plus and was wondering about all the ways you can use it.</p>
<p>I use it for probabilities - like ! nCr and nPr
And solving a equation equal to zero - like 2(sin x) + cos(x) - 2x + 11 = 0
I've read the manual which come with it, but it's pretty skimpy.</p>
<p>Anyways, tell me everything you know!</p>
<p>Um, for the SAT you really only need to use a calculator for graphs and calculations.</p>
<p>does the ti-84 have a solve function?</p>
<p>I'm not sure if it can solve functions. What are the ways you can use it for graphing? I heard people talking about using it to find parallel, perpendicular lines, etc but I'm not sure how to use it in such a manner.</p>
<p>I used to it to check multiplication after I was done. Anything more just wastes time.</p>
<p>I was thinking about writing a program with a list of prime numbers up to like 100 just in case they come up on the test... it would save the pain and time of figuring them out and checking.</p>
<p>Memorize the prime numbers up to 50 at most. Any more, especially wasting time programming, is counterproductive.</p>
<p>who says programs are a waste of time? Programs can help with speed...like quad, factors, and slope/midpoint/distance programs help you solve problems faster. You can use them to check your answer too. Besides, it doesn't take that much time to program if you know how to. It won't cost you time.</p>
<p>Can the TI-84 help you on this kind of problem?</p>
<p>f(g)= -{g(x)} Find the graph which represents this:
Where {} stands for "absolute value"</p>
<p>I don't know how to put in more than 1 variable - is it possible?</p>
<p>you don't need a calculator for the SAT... </p>
<p>if you need a calculator to do the problems, then you are approaching them the wrong way</p>

<p>Could not agree more.</p>
<p>Using graphing calculator programs is overkill... a good scientific calculator is enough. Especially a nice one like this

Natural display, factors quadratic and CUBIC functions for you with imaginaries (take that, benquad), it's light and slim, and you don't have to replace batteries!! :)</p>
