In this problem you'll explore how to evaluate the limit of a Riemann sum to calculate Vidx. Let's partition [0, 6] this way: P = 3 0, 6 . 1 6 . 4 6.9 6. 2 6(n - 1)2 n2 , 6 Answer the following questions: (a) Write a general expression for Ack in terms of k and n. Ack = (b) Fill in the blanks for the Riemann sum limit using this partition with Ck as the right endpoint of each interval [Ck-1, Ck] and evaluate the limit to compute / Vx dx. Vada = lim 12-+00 AIK 1 1 lim 1-+00 IN Enter an exact value (no decimals)
