Best ResponseYou've already chosen the best response.0OK so... Sin θ = 1/Csc θ so it would be 1/2 which is O/H? So the mesurements can be calculated using x^2 + y^2 = r^2?

Best ResponseYou've already chosen the best response.0as......... if ....secθ=2 hence ...1/cosθ=2 cosθ=1/2 sin(90+θ)=1/2

Best ResponseYou've already chosen the best response.1csc = 1/sin > 1/sin = 2 > sin = 1/2 cos^2 = 1sin^2 cos^2 = 1(1/2)^2 cos^2 = 3/4 cos = sqrt3/2

Best ResponseYou've already chosen the best response.0thought since sin would = 1/2 and csc = 2 then wouldn't it be 30?

Best ResponseYou've already chosen the best response.0would it be negative since it's in the II quadrant? and only thing positive in II quadrant is Sin and CSC?
