<p>Hi all,</p>

<p>while i was looking over my practice test just a second ago, my calculator just shut itself off. when i turned it on again it says "ram cleared" and all my programs are gone. Now i don't know what i'll need... I'm aiming for an 800 on the math, have been prepping with barron's book, the programs in that books doesn't seem very applicable. I know i'll need to use the quadratic formula. I had a conic ax^2+bxy+cx^2+dx+ey+f=0 graphing program, but my math teacher gave it to me so i don't know how to make it myself... and i don't know what else i'll need. I'm very calculator dependent.</p>

<p>This happened a few days ago but the calculator didn't reset. It didn't even say low battery... and the batteries are fresh from May. But anyways my mom's buying me some new batteries now.</p>

<p>Also ,other than the formulas, what do you guys recommend looking over for a pre-calc student as a last-minute memory refresher...</p>

<p>Thanks</p>

<p>The quadratic formula should've been memorized in Alg 1. </p>

<p>You don't need the conic grapher. Just know how to complete the square to find the (x-h)^2 + (y-k)^2 form. There won't be an xy term as far as I know (but if you must know, an xy term will "tilt" the graph).</p>

<p>EDIT: look over probability (permutations and combinations), sets, and "group" problems (e.g. out of X students, Y like apples, Z like oranges, and A like both. How many like neither)</p>
