In quadrant IV, the value of cos θ can be any positive number between 0 and 1. ;
If an angle lies in the fourth quadrant, then by the definition of trigonometric functions in the unit circle, the value of cosine (cos) will always be positive. This is because in the fourth quadrant, the x-coordinate of a point is positive and since cosine is the ratio of the adjacent side to the hypotenuse in a right-angled triangle, or the x-coordinate on the unit circle, we can infer that the value of cos will be positive.
In quadrant IV, the cosine of an angle is always positive, meaning it can take any value between 0 and 1, exclusive. As the angle approaches 360 degrees, cos approaches 1, while approaching 270 degrees means cos approaches 0. Therefore, cos ( θ ) in quadrant IV is positive and falls within the range of (0, 1).
