Directions: Show your work for full credit. If you need extra room, use the back of the opposite page, clearly indicating the problem number and your answer.

  1. Determine if the following limits exist and if so their value:
    1. limx®¥ [(3 x2+5-[2/x])/((x+3)2)]
    2. limx® 2+ [(x+2)/(x2-4)]
  2. Find an intermediate value c to verify the Mean Value Theorem for f(x) = x2+3 x-2 on the interval [1,3].

  3. Determine antiderivatives for each of the following functions:
    1. [(5x2-1)/(3x2)]
    2. [Ö(x-2)]

  4. Compute the integrals
    1. ò12 4x(x3-2x)  dx
    2. òx2 sin(x3+1) dx

  5. Evaluate each of the sums
    1. åj = 24 (3j2-j+1)
    2. åj = 140 (2j-1)

  6. Compute the area of the circumscribed rectangles using the function f(x) = 2x2-3 over the interval [0,2] using a uniform partition with n = 4.

  7. Compute the area between the curve y = sin(x) and the x-axis over the interval [0,p].

Extra Credit:  Use 3 interations of the Newton-Raphson algorithm to approximate 3Ö[` 3 ] with a starting value of x0 = 1.
