circle equation

(x-h)Â˛ + (y-k)Â˛ = rÂ˛

center = (h,k)

New cards

21

parabola vertex form equation

y = a(x-h)Â˛ + k

New cards

22

ellipse equation

((x-h)Â˛/aÂ˛) + ((y-k)Â˛/bÂ˛) = 1, or switch a and b around depending on direction of ellipse, a first when ellipse is wider on sides

b = distance from center to co-vertex

Foci = (hÂąc, k)

cÂ˛ = aÂ˛ - bÂ˛

New cards

23

hyperbola equation

((x-h)Â˛/aÂ˛) - ((y-k)Â˛/bÂ˛) = 1

a = distance from center to vertex

c = distance from center to foci

bÂ˛ = cÂ˛ - aÂ˛
