Question #355f8

Answer 1

see explanation.

Explanation:

`theta = -150^circ` is coterminal to `210^circ` or `(7pi)/6` radians.

This is a Unit Circle angle and you should memorize the sine and cosine:

`sin(210^circ) = -1/2`
`cos(210^circ) = -sqrt(3)/2`
`tan(210^circ) = -sqrt(3)/3`
`csc(210^circ) = -2`
`sec(210^circ) = -2/sqrt(3)`
`cot(210^circ) = -sqrt(3)`

Answer 2

For `ϴ = 150 °` the values of the 6 trigonometric functions ae given below :-

Explanation:

`sinϴ =1/2`

`cosϴ =-(3)^(1/2)/2`

`tanϴ = -(3)^(1/2)`

`cotϴ = -1/(3)^(1/2)`

`secϴ =-2/(3)^(1/2)`

`cosecϴ = 2`
