Finding Riemann Sum for f(x)=3x^2+3

Click For Summary
SUMMARY

The discussion focuses on calculating the Riemann sum for the function f(x) = 3x² + 3 over the interval [0, 6] with a partition defined by x₀ = 0, x₁ = 3, x₂ = 4, and x₃ = 6, using n = 3. Two methods are explored: (a) using the right end-point of each subinterval and (b) using the mid-point of each subinterval. The Riemann sum is defined as the sum of the function values at the chosen sample points multiplied by the width of the subintervals.
