1 Parametric curves Consider the parametric function r(t) = sin(t) y(t) = 2-sin(t) (1) Show that this traces a line segment in the (x, y) plane. What are the end-points of that segment? (Provide the z and y coordinates of both points). Coordinates of the first end point. Coordinates of the second end point (2) As the point (r(t), y(t)) travels on the segment, what is its distance to the origin. Call this the function D(t)? The distance to the origin is the function D(t) = (3) Using Calculus, find the time at which the point is closest to the origin, and show that it hap- pens on one of the end points.
