. Next, since the
transverse axis is vertical, we need to add and subtract the value of a
to the y--component of the center in order to calculate the vertices.
Thus, the vertices are 
and 
. The foci are found in a similar
fashion and are given by 
and 
.
The eccentricity of this hyperbola is
Last but not least, the equations of the asymptotes are
and
