The Basic Idea of Riemann Sums
Imagine you have a plot of land with one side that is an irregular curve. How would you calculate its area? One of the most practical ways is to divide the land into several rectangular pieces of the same width, calculate the area of each piece, and then add them all up.
That's the basic idea behind a Riemann Sum. It is a method to approximate the area of a region under a curve by dividing it into multiple rectangles and summing up their areas. The more rectangles we use, the more accurate our area approximation becomes.
Key Components
To perform a Riemann Sum, we need to understand its main components:
-
Interval : This is the left and right boundary of the region whose area we want to calculate.
