Example Question #1 : Riemann Sums
Find the Left Riemann sum of the function
on the interval divided into four sub-intervals.
The interval divided into four sub-intervals gives rectangles with vertices of the bases at
For the Left Riemann sum, we need to find the rectangle heights which values come from the left-most function value of each sub-interval, or f(0), f(2), f(4), and f(6).
Because each sub-interval has a width of 2, the Left Riemann sum is
