(1 point) Consider the function f(I) = 4 + 6. In this problem you will calculate 4 + 6 ) da by using the definition The summation inside the brackets is R, which is the Riemann sum where the sample points are chosen to be the right-hand endpoints of each sub-interval. Calculate Rn for f(x) = + 6 on the interval |0, 3] and write your answer as a function of n without any summation signs. You will need the summation formulas on page 369 of your textbook. We recall a few of those formulas here: n(n + 1) 2 n(n + 1)(2n + 1) ME i2 6 [(ca; + b;) = c ai 3i Hint: Ci - and Ar = 8 1 00 n Rn = lim Rn 1 +00
