Theorem
Let $\HH$ be a hyperboloid of one sheet.
Let $\HH$ be embedded in a cartesian $3$-space such that the conjugate axes of the hyperbolas forming its okane sections coincide with the $z$-axis.
The equation for $\HH$ can be expressed in the form:
- $\dfrac {x^2} {a^2} + \dfrac {y^2} {b^2} - \dfrac {z^2} {c^2} = 1$
where $a, b, c \in \R_{\ne 0}$.
