Key Concepts

Parametric Equations

Parametric equations describe a curve by expressing the coordinates of points on the curve as functions of one or more independent parameters. This method is useful for representing lines, curves, and other geometric objects in a form that easily indicates the motion or progression along the curve.

Direction Vector

A direction vector defines the orientation of a line or ray in space. It is typically obtained by subtracting the coordinates of a starting point from a second point on the curve, which gives the vector that points in the direction in which the curve progresses.

Ray

A ray is a half-line that begins at an initial point and extends infinitely in one direction. Unlike a full line, a ray only includes those points that can be reached from the starting point by moving along the direction vector, typically with a parameter constrained to non-negative values.
