For parametric equations x = a cos t and y = b sin t, describe how the values of a and b determine which conic section will be traced. 2. Explain how you would graph the following set of parametric equations by plotting points and describing the orientation. X = 3t and y = 2 3. The following two sets of parametric functions both represent the same ellipse. Explain the 1 difference between the graphs. x = 3 cos t and y = 8 sin t x = 3 cos 4t and y = 8 sin 4t
