Quadrants of sin cos tan

WebSine, Cosine and Tangent in Quadrant 4. Finally, when angle a is in Quadrant 4 (between 270° and 360°), the adjacent side is back along the positive x- direction, while the opposite … WebUse reference angles to find the values of cos (150°) and sin (315°). Since 150° is in quadrant II, the reference angle for 150° is, 180°-150°=30° where, cos (30°)=. Also because 150° is in quadrant II, cosine is negative then, cos (150°)=. Since 315° is in quadrant IV, the reference angle for 315° is, 360°-315°=45° where, sin⁡ (45)°=.
