so that the error in it will be less.
intigrals are the sum of all elements present in the volume.
so we will need to sum it by taking elements as small as possible.
consider we need to calculate area of a curve.
we can divide it in many rectangles of same width as shown in image.
we can assume area as sum of areas of all rectangles.
but the area will be right if we take the width of rectangles as small as possible.
