Step-by-step explanation:

2 { \cos(60) }^{2}  \cot(30)  + 6 {\sin(30)}^{2} { \csc(60)}^{2}  \\ 2 \times  \frac{1}{4}  \times  \frac{1}{ \sqrt{3} }  + 6  \times \frac{1}{4}  \times  \frac{4}{3}  \\  \frac{1}{2 \sqrt{3} }  + 2 \\  \frac{1 + 4 \sqrt{3} }{2 \sqrt{3} }

you can rationalize further by multiplying by 23.....answer will be 3+12/6
