#sin(150^o)=1/2#
#cos(150^o)=-sqrt(3)/2#
#tan(150^o)=-1/sqrt(3)#
#csc(150^o)=2#
#sec(150^o)=-2/sqrt(3)#
#cot(150^o)=-sqrt(3)#

Explanation:

#sin(150^o)=sin(30^o)=1/2#
#cos(150^o)=-cos(30^o)=-sqrt(3)/2#
#tan(150^o)=frac{sin(150^o)}{cos(150^o)}=-1/sqrt(3)#
#csc(150^o)=1/sin(150^o)=2#
#sec(150^o)=1/cos(150^o)=-2/sqrt(3)#
#cot(150^o)=1/tan(150^o)==-sqrt(3)#
