<p>i m taking plane trigonometry, and in the classes schedule book, it says that the TI-85/86 will be used, but i have a question that could i use the TI-84 plus silver for my class and what is the different between TI-86 and TI-84 plus silver ?</p>
<p>Years ago, there were two calculators--the TI-82 and TI-85.</p>
<p>The TI-82 was the lesser of the two. It evolved into the TI-83, TI-83 Plus, and more recently the TI-84 series (plus, silver, etc).</p>
<p>The TI-85 was a more advanced calculator with more advanced functions. It was eventually replaced by the TI-86.</p>
<p>These have always been two seperate calculators. The TI-84 is essentially a TI-83 Plus in a new case with more RAM and a few new features. The TI-86 is a higher powered machine that will always do more than a TI-84 no matter how plus or silver you can get it.</p>
<p>So the answer to your question is...no. You want a TI-86 (or a used TI-85).</p>
<p>Plane trig sounds to me like it will need more than a TI-84 will provide, but don't take my word for that (I've never taken plane trig and probably never will).</p>
<p>So a TI-85 is better than a TI-83 and TI-84?</p>
<p>dang, so i need a TI-86 which is more expensive T_T. I m so broken. .. . . . . .</p>
<p>maybe you should go ask your professor about that...
I personally think an TI-84 Silver works completely fine... I've taken AP Calculus with an TI-84 and it didn't slow me donw or anything.
but again, maybe the professor knows better or just look for an upper class student who have taken the same class you are currently taking...</p>
<p>Don't forget that textbooks sometimes are set up to one particular calculator. I used a TI-89 for stats and had to translate everything into terms for it since the book (Triola's text) was set up for a TI-83. (That text is one of my personal favorites, by the way).</p>
