Hint: apply Taylor expansion with the Lagrange Remainder on each interval [(i – 1)/n, i/n].
Remark 1: This gives the speed of convergence of the left Riemann sum.
Remark 2: We will learn that continuous functions are always Riemann-integrable so the assumption f E R[0, 1] is
unnecessary.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F1de81170-e7cf-4e92-bed5-a7f0f5dfddb4%2F65a07068-dd60-495a-b12e-dc8488dba3c7%2Fgr5wpr6_processed.png&w=3840&q=75)
