(a)

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

Construct a table with different values of $\"\"$ .

$\"\"$

Graph :

(1) Draw the coordinate plane.

(2) Graph the parametric equations $\"\"$ and $\"\"$ .

$\"\"$

Indicate the obtained points on the graph.

Based on the values of $\"\"$ , indicate the direction of $\"\"$ as it increases with an arrow.

$\"\"$

(b)

Solve for the value of $\"\"$ :

$\"\"$

Consider $\"\"$ .

Substiute the value $\"\"$ in the equation $\"\"$ .

$\"\"$

$\"\"$ because the parametric equation is $\"\"$ .

$\"\"$ .

Therefore, $\"\"$ , $\"\"$ .
