<p>The general quadratic equation in 2 variables has the form Ax^2 + Bxy + Cy^2 + Dx + Ey + F = 0</p>
<p>If B^2 - 4AC < 0 and A = C, the graph is a circle
If B^2 - 4AC < 0 and A is not equal to C, the graph is an ellipse
If B^2 - 4AC = 0, the graph is a parabola
If B^2 - 4AC > 0, the graph is a hyperbola</p>
<p>Aiming for 800. Do people who get 800s know this? I am pretty sure I never even learned this in school. This is from the Barrons Math Level 2 book (Conic sections section) </p>
<p>Also, any good sites for explaining hyperbolas?</p>
<p>@esthetique: What kind of calculator do you have, and how do you go about doing that? </p>
<p>I’m debating over studying the entire formulas section of the Barron’s book; my previous score in Math II was horrendous and I’m aiming for 750+.</p>
<p>I COMPLETELY winged the Math II and ended up with an 800. I didn’t memorize a single formula like that. The test is a piece of cake if you’ve taken calc.</p>
<p>Greed: Don’t be a jerk about it. I did horrendously the first time I took it and got a 790 after studying. It’s definitely possible to improve the score drastically, so it doesn’t have to be effortless. Some schools don’t have calc until senior year.</p>
<p>Put it in your calc by making a new program and typing it in. To see it, just “edit” that program.</p>
