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.

Famous quotes containing the word functions:
“When Western people train the mind, the focus is generally on the left hemisphere of the cortex, which is the portion of the brain that is concerned with words and numbers. We enhance the logical, bounded, linear functions of the mind. In the East, exercises of this sort are for the purpose of getting in tune with the unconsciousto get rid of boundaries, not to create them.”
—Edward T. Hall (b. 1914)
