1. Find the following limit of right Riemann sums by evaluating the definite integral that it represents:
limn→∞ k=1Σn (1 + (4k/n))(4/n)
2. Write down a right Riemann sum that approximates the following integral and evaluate the integral by finding the limit directly. Hint: the formulas for sums of positive integer powers will be helpful here.
0∫1 x2 dx
