Webcsc(θ) = − √ 5 1 sin(θ) = − √ 5 1 = − √ 5·sin(θ) or sin(θ) = − 1 √ 5 This tells us that θ must be in quadrant III or IV. We are also given cos(θ) < 0, so θ must be in quadrant II or III. Thus we know that θ is in quadrant III. We use this to draw a triangle to help us find the other trig functions of θ. From the ... WebIn general, if lies in the third quadrant, the acute angle θ − 180° is called the related angle for θ. The Fourth Quadrant Finally, if θ lies between 270° and 360° the corresponding point P is in the fourth quadrant. In this quadrant, we can see that the sine and tangent ratios are negative and the cosine ratio is positive.
