Compute the Riemann sum for f(x) = 21 a on [1, 4] using the partition P = {1,2, 2.5, 3, 4} and. • the left endpoint of each subinterval: • the midpoint of each subinterval: Now compute the Riemann sum for f(x) on [1, 4] using a partition with six equal-width subintervals and. • the right endpoint of each subinterval:

Use the Riemann Sum to find the area of the region bounded by the graph of f(x)=tan(x/6) and the x-axis between x = 0 and x = 2π. Write out the expression of the summation, but don’t evaluate it.

Find the right Riemann sum of f(x)=x²-1 on [2, 4] n = 4 Provide your answer below:.

Let f(x) = x², and compute the Riemann sum of f over the interval [3, 5], choosing the representative points to be the left endpoints of the subintervals and using the following number of subintervals (n). (Round your answers to two decimal places.) (a) Two subintervals of equal length (n = 2) (b) Five subintervals of equal length (n = 5) (c) Ten subintervals of equal length (n = 10) (d) Can you guess at the area of the region under the graph of f on the interval [3, 5]? 32.67 square units
