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)
