WebWhile summation notation has many uses throughout math (and specifically calculus), we want to focus on how we can use it to write Riemann sums. Example of writing a Riemann sum in summation notation Imagine we are approximating the area under the graph of f (x)=\sqrt x f (x) = x between x=0.5 x = 0.5 and x=3.5 x = 3.5.

For … WebA Riemann sum is an approximation of the area under a curve by dividing it into multiple simple shapes (like rectangles or trapezoids). In a left Riemann sum, we approximate the area using rectangles (usually of equal width), where the height of each rectangle is equal to the value of the function at the left endpoint of its base.
We know that the sum of two numbers is the result obtained by adding two numbers. Thus, if {x1,x2,…,xn}{x1,x2,…,xn} is a sequence, then the sum of its terms is denoted using the symbol Σ (sigma). i.e., the sum of the above sequence = ∑ni=1xi=x1+x2+….xn∑i=1nxi=x1+x2+….xn.
