Answer:
This means that after going around the unit circle once (2π radians), both functions repeat. So the period of both sine and cosine is 2π . Hence, we can find the whole number line wrapped around the unit circle.

Answer:
Circular paraboloid
Step-by-step explanation:
Given ,

Here, these are the respective  axes components.
 axes components.
- <em>Component along x axis  </em> </em>
- <em>Component along y axis  </em> </em>
- <em>Component along z axis  </em> </em>
We see that , from the parameterised equation , 
This can also be written as :

This is similar to an equation of a parabola in 1 Dimension.
By fixing the value of z=0,
<u><em>We get  which is equation of a parabola curving towards the positive infinity of y-axis and in the x-y plane.</em></u>
 which is equation of a parabola curving towards the positive infinity of y-axis and in the x-y plane.</em></u>
By fixing the value of x=0,
<u><em>We get  which is equation of a parabola curving towards positive infinity of y-axis and in the y-z plane. </em></u>
 which is equation of a parabola curving towards positive infinity of y-axis and in the y-z plane. </em></u>
Thus by fixing the values of x and z alternatively ,  we get a <u>CIRCULAR PARABOLOID. </u>
