Please see the explanation for 2 general examples.

A hyperbola with a horizontal transverse axis:

#(x-h)^2/a^2-(y-k)^2/b^2=1#

is tangent at its 2 vertices to the 2 ends of major axis of a parabola:

#(x-h)^2/a^2+(y-k)^2/b^2=1;a>b#

Where the values of a, h and k are the same for both equations.

A hyperbola with a vertical transverse axis:

#(y-k)^2/a^2-(x-h)^2/b^2=1#

is tangent at its 2 vertices to the 2 ends of major axis of a parabola:

#(y-k)^2/a^2+(x-h)^2/b^2=1;a>b#

Where the values of a, h, and k are the same for both equations.
