Homework Statement
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.
Homework Equations
I know (cos θ, sin θ)
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.
