Explanation Riemann Sum is defined as the approximation of the integral by computing the finite sum. Given: The function is f ( x , y ) = x + y and rectangle is given as R = [ 0 , 1 ] × [ 0 , 1 ] Formula: If the interval [ a , b ] is divided into n sub intervals, then the length of each side is given as Δ x = b − a n Riemann Sum is given as S = ∑ i = 1 n ∑ j = 1 m f ( x i ) Δ x i Calculation: Given that the partition is regular, thus each sub rectangle will have same length and breadth. Sides of the rectangles are given as follows: Δ x = 1 − 0 2 = 1 2 = 0.5 Δ y = 1 − 0 2 = 1 2 = 0.5 Area of sub rectangle, Δ A = 0.5 × 0.5 = 0.25 The rectangle and sub rectangles will be displayed as follows The mid vertices of sub rectangles are the below points P 11 = ( 0.25 , 0 .25 ) P 21 = ( 0.75 , 0 .25 ) P 12 = ( 0.25 , 0.75 ) P 22 = ( 0...

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 t…

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.

Chapter 16.1, Problem 2E

To determine

Compute the Riemann sum with $N = M = 2$ in order to estimate the double integral of the function $f (x, y) = \sqrt{x + y}$ over $R = [0, 1] \times [0, 1]$ using a regular partition and upper right vertices of the sub rectangles as sample points.
