Question

From the information given determine the quadrant in which the terminal point (determined by an angle with a measure of a) lies. Input I, II, III, or IV.

If sin(θ)<0 and cos(θ)<0), then (x,y) lies in quadrant ___

If sin(θ)>0 and cos(θ)<0), then (x,y) lies in quadrant ____

If sin(θ)>0 and cos(θ)>0), then (x,y) lies in quadrant ____

If sin(θ)<0 and cos(θ)>0), then (x,y) lies in quadrant ____

Answer 1

Refer to the answers below (and the attached file)

Explanation:

If sin(θ)<0 and cos(θ)<0, then (x,y) lies in quadrant III

If sin(θ)>0 and cos(θ)<0, then (x,y) lies in quadrant II

If sin(θ)>0 and cos(θ)>0, then (x,y) lies in quadrant I

If sin(θ)<0 and cos(θ)>0, then (x,y) lies in quadrant IV
