Can someone help me with this parametric art questions for calculus?

4. A nice family of Lissajous curves is generated by taking a to be an odd integer and b = +1. Match the following parametric equations with the curves in Figure 2. A: x = cos 5t, y = sin4t B: x = cos 3t, y = sin 4t C: x = cos 5t, y = sin 6t D: x = cos 9t, y = sin 8t Calc II Project - Parametric Art Spring 2020 (a) ( b ) (c) (d) Figure 2 5. Without graphing, describe the curve produced by the equations x = cos 10t, y = sin 10t. 6. What is the effect of introducing a phase angle in the equations? For example, plot and describe the curve x = cos | 5t+ y = sin 4t, in which the x-coordinate has the phase angle
