Match the statements/expressions in Column I with the statements/expression in Column II. Column I Column II Root(s) of the equation `2sin^2theta+sin^2 2theta=2` (p) `pi/6` Points of discontinuity of the function `f(x)=[(6x)/pi]cos[(3x)/pi],` where `[y]` denotes the largest integer less than or equal to `y` (q) `pi/3` Volume of the parallelepiped with its edges represented by the vectors ` vec a , vec ba n d vec c` are unit vectors satisfying ` vec a+ vec b+sqrt(3) vec c= vec0` (r) `pi/2`
