Hyperbolic Functions and Equations
Just as the sine and cosine functions give a parametric equation for the ellipse, so the hyperbolic sine and hyperbolic cosine give a parametric equation for the hyperbola.
As
one has for any value of that the point
satisfies the equation
which is the equation of a hyperbola relative its canonical coordinate system.
When μ varies over the interval one gets with this formula all points on the right branch of the hyperbola.
The left branch for which is in the same way obtained as
In the figure the points given by
for
on the left branch of a hyperbola with eccentricity 1.2 are marked as dots.

“Empirical science is apt to cloud the sight, and, by the very knowledge of functions and processes, to bereave the student of the manly contemplation of the whole.”
—Ralph Waldo Emerson (18031882)
