(P) Equation - Horizontal(x-h)^2 = 4p(y-k)
(P) Equation - Vertical(y-k)^2 = 4p(x-h)
(P) Standard Equation (horizontal)ax^2 + by + c = 0
(P) facing up or to the right when _ and down and left when _positive - negative
(P) Focus - horizontal - vertical(h,k+p) - (h+p,k)
(P) Directrixy = k-p
(P) Vertex(h,k)
(E) Equation - Horizontal(x)^2/(a)^2 + (y)^2/(b)^2 = 1 (Always 1)
(E) Equation - Vertical(X)^2?(b)^2 + (Y)^2/(a)^2 = 1 (Always 1)
(E) Vertices - horizontal - verticalH = (h+-a,k) - V = (h,k+-a)
(E) Foci - Hor - VerH = (h+-c,k) - V = (h,k+-c)
(E) equation for cc^2 = a^2 - b^2
(E) Eccentricity equation e = c/a
(H) Equation - Horizontal(X)^2/(a)^2 - (Y)^2/(b)^2 = 1 (Always 1)
(H) Equation - vertical(Y)^2/(a)^2 - (X)^2/(b)^2 = 1 (Always 1)
(H) Midpoint is the _ and is written _Center - (h,k)
(H) Vertices - Hor - VerH = (h+-a,k) - V = (h,k+-a)
(H) Foci - Hor - VerH = (h+-c,k) - V = (h,k+-c)
(H) Asymptotes - hor - ver(y-k) = (+-b/a)(x-h) - (x-h) = (+-b/a)(y-k)
