riemann sum equation explained A Riemann sum is an approximation of a region s area obtained by adding up the areas of multiple simplified slices of the region It is applied in calculus to formalize the method of exhaustion used to determine the area of a region
These sorts of approximations are called Riemann sums and they re a foundational tool for integral calculus Our goal for now is to focus on understanding two types of Riemann sums left Riemann sums and right Riemann sums Summation notation or sigma notation allows us to write a long sum in a single expression While summation notation has many uses throughout math and specifically calculus we want to focus on how we can use it to write Riemann sums

The basic idea behind a Riemann sum is to break up the domain via a partition into pieces multiply the size of each piece by some value the function takes on that piece and sum all these products What are Riemann sums A Riemann sum is an approximation of the area under a curve by dividing it into multiple simple shapes like rectangles or trapezoids
How can we use a Riemann sum to estimate the area between a given curve and the horizontal axis over a particular interval What are the differences among left right middle and random Riemann sums How can we write Riemann sums in an abbreviated form A Riemann sum is defined for f x f x as n i 1f x i x i 1 n f x i x Recall that with the left and right endpoint approximations the estimates seem to get better and better as n n get larger and larger The same thing happens with Riemann sums Riemann sums give better approximations for larger values of n n
