alaina's reflection

Okay, so this week I have been completely bogged down with studying for exams and keeping up with notes and homework in everything else. And, I almost forgot to do my reflection. So here goes.

First, I understand conics a lot better than I did last year, or durring the summer.
Circle
(x-h)^2+(y-k)^2=r^2
I always thought circles were easiest.

• Your center is (h,k)
• radius=r; take square root of r^2
• to graph, plot your center and count your radius all the way around.

Ellipse

(x^2+h/a^2)-(y^2+k/b^2)=1

• Your center is (h,k)
• Your major axis is the non-negative denominator
• minor is negative

Hyperbola

(x^2-h/a^2)+(y^2-k/b^2)=1

• Your center is (h,k)
• your major axis has the larger denominator

Parabola

y-y⊂1&sub/=m(x-x&sub/1)

**don't understand**

not much. There are certain little things that I keep blanking out on, but for the most part, I think I've got it. I'm really stressed out about this exam, though. I've been studying for 6 hours and it seems the more that I study, the more I forget. So I've put away the books for the night. Hopefully when I wake up in the morning, everything will be alright. I'll continue to study throughout the day, until the exam... I'll probably have questions in the morning. Night all.
