<p>i have a ti-89, and i was wondering what i should do to prep my calculator for the test.</p>
<p>does anyone know how to program in equations so you can just plug in and get the answer?</p>
<p>should i do anything else?</p>
<p>i had trig program :P
it was like just typing the amount of 2 angles+ 1 side, 3 sides, 2 sides+ 1 angle, etc... and it will find the areas and other missing value automatically.
even though there is only 1-2 questions ask to find something like that, but it helps you to solve problems quicker :D
here is the URL; you can either download it or make by yourself

<p>btw, quadratic formula equation is also helpful</p>
