Explanation Definition used: Let f be defined on a closed interval [ a , b ] , which is divided into n sub-intervals of equal length and x k * is any point in the k th subinterval [ x k − 1 , x k ] for k = 1 , 2 , ⋯ , n , then the Riemann sum on [ a , b ] can be written as ∑ k = 1 n f ( x k ) Δ x . It is known that Δ x is always positive

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
