In the first place an equation doesn't

If you mean, "find the equation for the normal to the curve given by r(t) = <acos t , bsin t> for any t", then say so.

Heres' a major hint the vector <a, b> is always normal to the vector <-b, a>.

In order to have a normal, you need to give us 1 set of coordinates.
