What we learned:

Parabolas

- vertex (h,k), a directrix (straight line, fixed distance from vertex), and focus(fixed distance from vertex)
- Standard form VERTICAL:

- Standard form HORIZONTAL:

- When 4p, also known as a, is greater than 1 the parabola is wide.
- When 4p is less than 1 the parabola is skinny.

Ellipses

- center (h,k), Vertices's (endpoints on Major axis), major axis (length of 2a), semi-major axis (length of a, center to one of the vertices's), Minor axis (legnth of 2b), Semi-minor (length b),Foci (c units from center), Focal radi (distance b/w Foci and point on ellipses.
- The midpoint of two foci would center of ellipses.
- Standard form HORIZONTAL:
- Standard form VERTICAL:
- a^2 is the bigger number.
- c^2 = a^2 - b^2

- center (h,k), Transverse axis (the distance b/w the vertices's, which are also the vertex. Is the difference of foci to pt, foci2 to pt. length of 2a), semi-transverse axis ( a),conjugate axis (length of 2b), Sem-iconjigate (b), Foci (c units from center), asymptotes.
- Standard form HORIZONTAL:
- Standard form VERTICAL:
- c^2 = a^2 + b^2
- When given slope of asymptotes, you can figure out the value of b or a. b/a = rise over run.

study hard guys!
