<p>I'll be taking the SAT Math 2 this week. Just wondering, what are some useful apps that can come in handy during the test?</p>
<p>Polynomial Root Finder is really the only thing you need.</p>
<p>Also, be sure to know which functions to use on your calculator for specific questions.</p>
<p>For ex: Limits. Press F3, then 3, then plug in the expression, followed by a comma and the variable used in the expression. Then, add one more comma after it, and write in the value that the limit is approaching to. Here’s what it would look like when you are trying to find the limit of x/(x+1) as x approaches to 1: limit(x/(x+1),x,1). You should get 1/2.</p>
