Integral Calculus – II

Integral Calculus – II Archimedes ( BC(BCE)- BC(BCE)) axes. We can also calculate the area between two given curves. . . Geometrical Interpretation of Definite Integral as Area under a curve: Suppose we want to find out the area of the region which is bounded above by a curve y ( ) , below by the x axis and the lines x and x Now from Fig . let the interval a b  is divided into n subintervals xi xi   , of equal length D x i i e i i xi = ∆ − for any xi xi xi ′ ∈   , let f x i ′
