Answer» csc(x)^2 - cot(x)^2 = 1 (cot(x)^2 - 3) / (csc(x) - 2) =>(csc(x)^2 - 1 - 3) / (csc(x) - 2) =>(csc(x)^2 - 4) / (csc(x) - 2) =>(csc(x) - 2) * (csc(x) + 2) / (csc(x) - 2) =>csc(x) + 2 x -> pi/6 csc(pi/6) + 2 =>1/sin(pi/6) + 2 =>1/(1/2) + 2 =>2 + 2 =>4

Answer»

csc(x)^2 - cot(x)^2 = 1

(cot(x)^2 - 3) / (csc(x) - 2) =>(csc(x)^2 - 1 - 3) / (csc(x) - 2) =>(csc(x)^2 - 4) / (csc(x) - 2) =>(csc(x) - 2) * (csc(x) + 2) / (csc(x) - 2) =>csc(x) + 2

x -> pi/6

csc(pi/6) + 2 =>1/sin(pi/6) + 2 =>1/(1/2) + 2 =>2 + 2 =>4
