Hi
%28y%2B2%29%5E2%2F3%5E2-%28x-1%29%5E2%2F4%5E2=1
center: (1,-2)
vertices(b=3): (1,1) and (1,-5)
foci: |sqrt(9+16)| = 5, F(1,3) and (1, -7)
Standard Form of an Equation of an Hyperbola opening up and down is:
%28y-k%29%5E2%2Fb%5E2+-+%28x-h%29%5E2%2Fa%5E2+=+1 with C(h,k) and vertices 'b' units up and down from center,
Foci sqrt%28a%5E2%2Bb%5E2%29units units up and down from center, along x = h
