If sin theta= 0.3090 , what is the approximate value of csc theta ?

Question

0.5559

1.3090

3.2362

10.4733

Answer 1

Hi Mel,

The main part of the question is knowing the relationship between sin(θ) and csc(θ). This is one of those reciprocal identities, namely, csc(θ)=1/sin(θ). Does that look familiar? If you have this identity, and use the given information about sin(θ), do you see how to finish the problem?
