(a) True or false? The same curve can be described by parametric equations in many different ways.
O True
False
(b) The parametric equations x = 2t, y = (2t)² model the position of a moving object at time t. When t =
0, the object is at
and when t = 1, the object is at
(c) If we eliminate the parameter, we get the equation
which is the same as the equation for the path of
object with parametric equations x = t, y = t², t> 0. So the two
objects move along the same path but traverse the path differently. Indicate the position of each object when t = 0 and whent = 1 on a graph. (Let A be the object whose motion is given by the
parametric equations x = t, y = t2, and let B be the object with equations x = 2t, y = (2t)².)
