Definite Integral

Additional Mathematics

The definite integral of a function f (x) with respect to x with the interval from x = a to x = b

For the functions f (x)

where k is a constant

where a < b < c

The total area of the shaded region = Area of the region K + Area of the region H

Area of a region between the curve and the x-axis

The negative sign of the value of the definite integral

is only used to indicate that the area is under the x-axis

Area between the curve and the y-axis
