Q6

1. x = e^t(sin t + cos t), y = e^t (sin t - cos t)

   Solution

   
2. x = a (θ + sin θ), y = a (1 - cos θ)

   Solution

   
3. x = a (1 - cos θ), y = a (θ + sin θ)

   Solution

   
4. x =
   1+log t / t²
   ,y=
   3+2log t / t

   Solution

   
5. x = 3 cos θ -2 cos³θ,y=3sinθ-2 sin³ θ

   Solution
