Normal would be vertical line parallel to y axis, hence its slope would be undefined.
Explanation:
this gives
At t=
The slope at t= pi/2 is thus 0, that means the tangent is a horizontal line that is parallel to x axis.
The normal to this horizontal tangent would thus be a vertical line. Its slope would therefor be undefined,
