Consider the parametric equations x = cos 2t, y = cos t for 0stsn.H a. Eliminate the parameter to write a rectangular (Cartesian) equation for the curve. Your final equation must NOT contain any trig functions or inverse trig functions. b. Fill in the table below and then use these values to sketch a graph of the curve defined by the parametric equations in the xy-plane. On your graph, use arrows to show the direction of increasing t. y 4 2 37 4 tttttt
