find and equation for a hyperbola with vertices at (2,3) and (2,-1) and foci at (2,6) and (2,-4)
hyperbola has a vertical transverse axis.
Its standard form of equation: %28y-k%29%5E2%2Fa%5E2-%28x-h%29%5E2%2Fb%5E2=1, (h,k)=(x,y) coordinates of the center
For given hyperbola:
x-coordinate of center=2
y-coordinate of center=1 (midpoint of vertical transverse axis)
center: (2,1)
a=2 (distance from center to vertices)
a^2=4
c=5 (distance from center to foci)
c^2=25
c^2=a^2+b^2
b^2=c^2-a^2=25-4=21
Equation of given hyperbola:
%28y-1%29%5E2%2F4-%28x-2%29%5E2%2F21=1
