Question

What are the six trig function values of `150`?

Answer 1

`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)`
