The area bounded by the curve y = cosx, x-axis, ordinates x = π/2 and x = π is

Ordinates are the vertical coordinates of points in a Cartesian plane. They represent the y-values in an ordered pair (x, y) and measure the distance from the x-axis. Positive ordinates lie above the x-axis and negative ordinates lie below. They ...
