The area of the region bounded by a function y = f (x), the x-axis, and the two vertical boundaries i.e. ordinates x = a and x = b, can be determined by evaluating the definite

integral

(1) If the f (x) ³ 0 on [ a,b ], then the area

          i.e. area of the region below the graph y = f (x), above x-axis and between the ordinates x = a and x = b is
