WebFinal answer. Transcribed image text: (4 points) Suppose A is in Quadrant II and B is in Quadrant II. If sin(A)= 6160 and cos(B) = −419, then sin(A+B) = Compute sin(A−B) = Remark: Your answers cannot contain trigonometric functions. … WebThe 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. To find the sine and cosine of 330° we locate the corresponding point P in the fourth quadrant.
