Riemann integral

The Riemann Integral is a method for determining the area under a curve on a graph. Imagine breaking the area into thin, vertical slices or rectangles. By calculating the area of these rectangles and summing them up, you can approximate the total area. As the width of the rectangles becomes very small (approaches zero), this approximation becomes more accurate. The Riemann Integral formalizes this process mathematically, allowing us to analyze functions and find areas, which is fundamental in calculus and various applications in science and engineering.
