A curve has the parametric equations
x=sin2tx = \sin^2 tx=sin2t, y=sin2ty = \sin 2ty=sin2t, where 0<t<π0 < t < \pi0<t<π
Find an expression for dydx\displaystyle \frac{dy}{dx}dxdy in terms of ttt.
Find an equation for the normal to the curve at the point where t=π6\displaystyle t = \frac{\pi}{6}t=6π.
