Spring ’99 Calculus II; Quiz 4 section 51

  1. Print your name:
  2. Find the volume of the solid obtained by rotating about the x-axis the region bounded by the curves y = tan(x) sec(x), the x-axis, x = 0 and x = π/4.

Spring ’99 Calculus II; Quiz 7 section 51

  1. Print your name:
  2. Determine whether or not the sequence an =

n · ln(n) n^2 + 1

converges. If it converges, find

its limit.
