For the hyperbola represented by [(y+2)^2]/4 - [x^2]/12=1 find the foci and vertices

Given hyperbola has a vertical transverse axis.
Its standard form of equation: , (h,k)=coordinates of center
for given hyperbola:
center: (0,-2)
a^2=4
a=2
vertices: (0,-2�a)=(0,-2�2)=(0,-4) and (0,0)
b^2=12
c^2=a^2+b^2=4+12=16
c=√16=4
foci: (0,-2�c)=(0,-2�4)=(0,-6) and (0,2)
