Exam questions on Parametric equations

  1. A curve CC has parametric equations x=3t−1x=3t-1, y=t2+2y=t^2+2, where tt is a real parameter.
    Find the coordinates of the points where CC meets the line y=11y=11.2 marks
  2. A curve DD has parametric equations x=3sin⁡tx=3\sin t, y=2cos⁡ty=2\cos t, for 0≤t<2π0\leq t<2\pi.
    Find the coordinates of the points where DD meets the yy-axis.2 marks
  3. A ball is thrown so that, tt seconds later, its horizontal distance is x=20tx=20t metres and its height is y=15t−5t2y=15t-5t^2 metres, for t≥0t\geq0 until it lands.
    Find a Cartesian equation of the path of the ball, in the form y=f(x)y=f(x).3 marks
