alaina's makeup blog for 28 March 2010

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**

sigma notation i could use a little help on, also INTEGRAL COOEFFICIENTS!!!
