I wanted to find out what a "ponit" function was!
An important example of a "point function" is the function that assigns, to every non-negative real number t, the point on the unit circle on a Cartesian coordinate system at distance t around the circumference of the circle, counterclockwise or if t< 0, the clockwise.
Separate names with a comma.
