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 :
.
Sqyaring on both sides.
\Substiute the value in .
Therefore, the cartesian equation of the curve is .
