WebThe values we use for i i are different for left and right Riemann sums: When we are writing a right Riemann sum, we will take values of i i from 1 1 to n n . However, when we are writing a left Riemann sum, we will take values of i i from 0 0 to n-1 n −1 (these will give us the value of f f at the left endpoint of each rectangle). Problem 1.A WebIn 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. In a right Riemann sum, the height of each rectangle is equal to the value of the function at the right endpoint of its base.
