Example: Parametric equation of a circle

The following example is used.

A curve has parametric equations x = sin(t) – 2, y = cos(t) + 1 where t is any real number.
Show that the Cartesian equation of the curve is a circle and sketch the curve.

Example: Parametric equation of a parabola

The following example is used.

A curve has parametric equations x = cot(t) + 1 , y = cosec2(t) – 4 where 0 < t < π

Show that the Cartesian equation of the curve is a parabola and sketch the curve.
