An equation using parameters to define x and y coordinates.
It acts as an independent variable for x and y.
They describe complex curves difficult in Cartesian form.
x = t, y = t² gives points forming a parabola.
x = cos θ, y = sin θ represent a unit circle.
Solve for parameter in one equation, substitute into another.
Lines, circles, parabolas, hyperbolas, and figure eights.
Modeling paths of moving objects or projectile motion.
It modifies the curve's extent, speed, or direction.
Use correct trigonometric functions for axes lengths.
