Step 1:

The parametric equation are $\"\"$ over the interval $\"\"$ .

Observe that $\"\"$ .

So $\"\"$ .

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

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

Now plot the graph for parametric equation $\"\"$ over $\"\"$ .

$\"\"$

Indicate the obtained points on the graph.

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

(b)

The parametric equation are $\"\"$ over the interval $\"\"$ .

Let us take $\"\"$ .

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

$\"\"$ .

So the Cartesian equation is $\"\"$ .
