1. Answer:

   sin theta equals to root 3 by 2 then cos theta equals to 2 by root 3

   then tan equals to 3 by 4

   then cot equals to 4 by 3

   2 cos squared theta equals to 32 by 9

2. Answer:

   sin theta =√3/2

   sin 60°=√3/2

   theta = 60°

   2 cot² theta -1 = 2 cot² 60°-1

   = 2 × ( 1/√3)² -1

   = 2/3 -1

   = (2 -3 )/3= -1/3
