WebCosine is negative in two quadrants: quadrants 2 and 3 (the left quadrants, where x is negative). The only quadrant that shares both qualities is quadrant 3. WebSo this point would lie in Quadrant IV. To plot this point on the coordinate plane, we will follow these steps: Step 1: Identify the x-coordinate of the given point. In this case, it is 4. Step 2: Start from the origin and move towards by 4 units on the positive x-axis.
