TI-89 for Math 2c

Test Preparation
3

<p>twilightdarling - ask anybody who’ve used TI-89 on SAT Math Level 2 - they will never go back to TI-83/84.</p>

<p>The most useful function is “solve”: you don’t need bother with graphing to find the riits of equations.</p>

<p>Two others - “expand”, simplifies algebraic expressions, and “factor” - does just what it says.</p>

<p>Try it on various practice tests you can find (I suggest “Real Subject Tests” and Spark Notes: similar to real content but about 50 points easier).
You’ll see that TI-89 might save you up to 5 min.</p>

<p>A good book for mastering the basics was published in August - “TI-89 for Dummies”
