The standard form of the equation of a hyperbola centered
at (h, k), with the transverse axis parallel to the x-axis and the
conjugate axis parallel to the y-axis, is
The length of the transverse axis parallel to the x-axis is 2a.
The length of the conjugate axis parallel to the y-axis is 2b.
The vertices are V 1 (h - a, k) and V 2 (h + a,
k).
The co-vertices are (h, k - b) and (h, k + b).
The foci are F 1 (h - c, k) and F 2 (h + c, k),
which are on the transverse axis.
