5 The parametric equations of a curve are
$$x = \mathrm { e } ^ { 2 t } , \quad y = 4 t \mathrm { e } ^ { t }$$
(i) Show that $\frac { \mathrm { d } y } { \mathrm {~d} x } = \frac { 2 ( t + 1 ) } { \mathrm { e } ^ { t } }$.\\
(ii) Find the equation of the normal to the curve at the point where $t = 0$.
