Suppose that vector lies in quadrant ii, quadrant iii, or quadrant iv. How can you use trigonometric ratios to calculate the direction (i. E. , angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than in each case.

What is likely to happen if a new aggregate demand curve moves to the right? prices and output would drop, and the equilibrium point will stay the same. prices would rise, and output would drop in the short run. prices and output would rise, and the equilibrium point will change. prices would rise, and output would drop in the long run.
