A curve has the parametric equations
x=sin2t,y=sin2t,0<t<π x = \sin^2 t, \quad y = \sin 2t, \quad 0 < t < \pi x=sin2t,y=sin2t,0<t<πFind an expression for dydx\displaystyle \frac{dy}{dx}dxdy in terms of ttt.
Find an equation of the normal to the curve when t=π6\displaystyle t = \frac{\pi}{6}t=6π
Find a cartesian equation for the curve.
Practise AQA A Level Maths 1.6 C: Coordinate geometry in the (x, y) plane with exam-style questions for A Level Maths. 110 questions covering 1.6.1 Equation of a straight line, 1.6.2 Coordinate geometry of the circle, 1.6.3 Parametric equations of curves (A-level only), and 1.6.4 Parametric equations in modelling (A-level only), matched to the AQA A Level Maths (7357) specification and written in Paper 1, Paper 2 and Paper 3 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
