Answer:
This is an ellipse.
Step-by-step explanation:

Applying the angle values in intervals of right angles (90°), the resulting set of values for z are:

(again)
If you look at the plot, you will observe how these values represent points in the xy plain. All of them belong to either the x or the y axis.
The resulting figure for the whole set of values of
is in fact an ellipse.
