cot n=-sqrt(3)

Write the principal solution of cot x=(-sqrt3) ?

The set of values of a for which (sqrt(a^(2)-3a)-2)cot x<=(sqrt(3))^(2016)x varepsilon R-{n pi,n varepsilon I} is

cot x =- sqrt3

If (cot theta-cos theta)/(cot theta+cos theta)=(2-sqrt(3))/(2+sqrt(3)) and ^(@)0

(cot theta-cos theta)/(cot theta+cos theta)=(2-sqrt(3))/(2+sqrt(3))
