Question

Assume t is defined for all time. Enter the letter of the graph below which corresponds to the curve traced by the parametric equations. Think about the range of x and y, and whether there is periodicity and or symmetry.
1. x=t+sin5t;y=t+cos5t
2. x=6cost+cos4.5t;y=6sint−sin4.5t
3. x=11+t^2cost2;y=11+t^2sint2)
4. x=cos5t;y=sin3t
5. x=t^3/4−t+1;y=t^2/4−1
