<p>Are there a list of programs I can download to my TI84 Plus that will help me on the Math II exam I'm taking in November? Would having a TI89 or an Nspire CAS increase my score significantly? If having a TI89 is really that helpful I'm willing to drop like $100 to get it for this test.</p>
<p>I can’t comment on the usefulness of a Ti89 or Nspire CAS, but I can tell you about the TI84 plus. There are some programs out there that can save you time. I’ll list the ones that helped me:</p>
<ul>
<li>Quadratic Formula (You plug in the A,B,C values of a quadratic AX^2+BX+c and it outputs the roots)</li>
<li>Distance and midpoint calculator (in 2d or 3d) - you input 2 points in 2d or 3d, and it outputs the distance and midpoint
-Sequences (Arithmetic and Geometric) - Helpful if you forget the equations, and it quickly calculates the desired term and series</li>
</ul>
<p>You either make them on your own, or DL them off "<a href="http://www.ticalc.org/pub/83plus/basic/math/“>http://www.ticalc.org/pub/83plus/basic/math/</a>” and put them into your calculator</p>
<p>Don’t forget that you can store info into your calculator in case you forget something. I recommend that you learn everything beforehand so you don’t have to search through your calculator on test day for the info you need, but it’s there as a last resort.</p>
<p>I must also say that you should learn the In’s and out’s of your calculator’s stock functions like how to find max and min of a function, how to use logs, how to graph correctly, how to find intersections, how to evaluate a function y1 at any x value, etc.</p>
<p>Alright cool, are there any good websites or guides that can give me a basic overview of commonly tested calculator programs on the Math II?</p>
<p>Just fyi, using a Ti-89 is NOT an advantage if you are not used to it. You’ll just waste time getting odd errors, so don’t get one just for the test.</p>
<p>Also, probably half of the Math II test cannot be solved by a calculator or is slower with a calculator…</p>
