Parametric Coordinates of a Hyperbola
For:
$$\frac{x^2}{a^2}-\frac{y^2}{b^2}=1$$
a point on the hyperbola can be represented as:
$$P(a\sec\theta,b\tan\theta)$$
using:
$$\sec^2\theta-\tan^2\theta=1$$
Terminology
- $$\theta$$ → Parametric angle.
Usage
- Used to represent points on a hyperbola and simplify tangent, normal and chord calculations.
