ssessment 1 of 2 7. Explain how you would graph the following set of parametric equations by plotting points and (4 points) describing the orientation. x = 3t and y=2 8. For parametric equations x = a cos t and y = b sin t, describe how the values of a and b (2 points) determine which conic section will be traced.9. The following two sets of parametric functions both represent the same ellipse. Explain the (4 points) difference between the graphs. x = 3 cos t and y = 8 sin t x = 3 cos 4t and y = 8 sin 4t
