Let f(x)=9-x^2 Consider the region under the graph on [0,3] and bounded by the x-axis. Divide this region into 6 subintervals and compute an estimate of the area using left endpoints for each partition.

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…

Bernhard Riemann's integral was the first systematic description of the integral of a function on an interval in the branch of mathematics known as real analysis.
