Question

3. If csc θ = ‒2, what is the value of sin θ?

Answer 1

`sin(theta)=-(1)/(2)`

Explanation:

Not sure if your teacher/profession mention this but you have to remember/learn the reciprocal property of identities. I copy this image online to demonstrate reciprocal property identity.

`csc(\alpha) = -2\\\\(1)/(sin(\alpha)) =(-2)/(1) \\\\(sin(\alpha))/(1) =(1)/(-2) \\\\sin(\alpha )=-(1)/(2)`
