Consider the function y= √x over the interval [0,9]. (a) Use a Riemman sum with a partition of [0,9] into three equal-length subintervals to estimate the area under the y= √x over the interval [0,9]. Use the right-hand endpoints of the subintervals to calculate the height for the rectangles. (b)Check your estimate from part (a) by integrating an appropiate integral to find the exact area
Riemann Sum
Riemann Sums is a special type of approximation of the area under a curve by dividing it into multiple simple shapes like rectangles or trapezoids and is used in integrals when finite sums are involved. Figuring out the area of a curve is complex hence this method makes it simple. Usually, we take the help of different integration methods for this purpose. This is one of the major parts of integral calculus.
Riemann Integral
Bernhard Riemann's integral was the first systematic description of the integral of a function on an interval in the branch of mathematics known as real analysis.
