Questions on the half-sheet - Ellipses and Hyperbolas
HYPERBOLAS VS. ELLIPSES
Ellipses
- the a-value is the BIGGER value
- whichever one it is under (x or y) tells you whether it is horizontal or vertical
- a^2 - b^2 = c^2
Hyperbolas
- the a-value is the FIRST one that you see
- if x comes first it is horizontal, if y comes first it is vertical
- a^2 + b^2 = c^2 (careful, different than ellipses formula)
