Question

Please need help urgently. Please show the steps as well. I don't completely understand the concept.

1- Graph each pair of parametric equations.
x=3 sin^3t
y=3 cos^3t

2-graph each pair of parametric equations.
x=7sin t+ sin 7t
y=7 cos t+ cos 7t

3-Graph each parametric equations.
x=2t
y=t+5, -2 more than or equal to t more than or equal to 3

4-Graph each pair of parametric equations.
x=2t-1
y=t^2+5,-4 more than or equal to t more than or equal to 4

5- Graph each pair of parametric equations.
x=6 sin t
y= 6 cos t, 0more than orequal to 2pi
