Riemann Sums and Function Values

The video tutorial explains how to calculate the Riemann Sum for the function f(x) = -x^2 + 16 using specific partitions. It discusses the concept of partitions, the significance of right endpoints, and how to calculate the area of rectangles formed by these partitions. The tutorial also covers the calculation of function values at specific points and how these values contribute to the Riemann Sum. The video concludes with the final calculation of the Riemann Sum, emphasizing the interpretation of negative areas.
