$\"\"$

The parametric equations are $\"\"$ and $\"\"$ .

(a) Construct a table for $\"\"$ and $\"\"$ .

\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \

$\"\"$

(b)

Graph:

(1) Draw the coordinate plane.

(2) Plot the $\"\"$ points obtained in the table.

(3) Connect the point using a smooth curve.

$\"\"$

(c) Graph:

Graph the parametric equations $\"\"$ and $\"\"$ .

$\"\"$

(d) Find the rectangular equation.

Consider $\"\"$ .

Squaring on both sides.

$\"\"$

Substitute $\"\"$ in $\"\"$ .

$\"\"$ .

The rectangular equation is $\"\"$ .

Graph the function $\"\"$ is

$\"\"$

Observe the graph:

Both the graphs seems to be similar on the interval $\"\"$ .
