Solution :
We have been given a parametric curve :
x = sin t , y = cos t , 0 < t < π
In order to determine concavity of the given parametric curve, we need to evaluate its second derivative first.
Therefore,



Taking double derivatives of the above equation:




For the concave up, we have


∴ 
For the concave down, we have
