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. $x=\frac{1}{1+t^2}\cos(t^2);\quad y=\frac{1}{1+t^2}\sin(t^2))$
 2. $x=\cos(5t);\quad y=\sin(3t)$
 3. $x=\frac{t^3}{4}-t+1;\quad y=\frac{t^2}{4}-1$
 4. $x=|\cos(t)|\cdot\cos(t);\quad y=|\sin(t)|\cdot\sin(t)$
 5. $x=6\cos(t)+\cos(4.5t);\quad y=6\sin(t)-\sin(4.5t)$
