(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

1) If the point (-4, 2) lies on the terminal arm of an angle θ in standard position, determine the exact value of csc θ.

2) If sec θ = -5/3 and angle θ terminates in quadrant III, which point must be on the terminal side of θ?

3) If cos θ = 5/13, where θ is in quadrant VI, determine the value of cot θ

4) Determine csc θ if (-10, 24) lies on the terminal arm of angle θ in standard position.

2. Relevant equations

I know (cos θ, sin θ)

3. The attempt at a solution

Well for #1, I thought you're supposed to csc(2) since csc θ is 1/sin θ but it's not, and the answer is [tex] \sqrt {5} [/tex] and I have no idea how you get that.

Thanks for any help.
