Directions: Show your work for full credit. Clearly indicate in your work the problem number and your answer.

  1. Determine if the following limits exist and if so their value:
    1. limx®1 [(x2-3x+2)/(x2-1)]
    2. limx®¥ [(3x2+sin(x))/(1-x2)]
    3. limx® 0 [(cos(x)-1)/x]
    4. limx® 3- [1/(x2-9)]
  2. Using the definition of derivative and properties of limits, compute f¢(1) where f(x): = 2+x-x2.

  3. Determine derivatives for each of the following functions:
    1. f(x) = (x2-1),
    2. [Ö(3x3-4x+1)]
    3. [Ö(sin(3x2))]

  4. Using differentials, estimate cos(.05).

  5. If the width of a rectangle is changing at a rate of twice its length and its length is changing at a rate of +5 cm/sec, then at what rate is the area of the rectangle changing?

  6. Consider the function

    f(x) = x3-x2-x+2,        -2 £ x £ 4.
    1. Determine the intervals where f is increasing and where it decreases.
    2. Determine the critical points for the function.
    3. Determine the intervals where f is concave up and where it is concave down.
    4. Specify which points are local maxima, local minima, or inflection points.
    5. Sketch a graph of f using the information determined above.

  7. Evaluate each of the antiderivatives:
    1. (2x2-3)(x2+2x)
    2. x[Ö(3-x2)]
    3. tan(x) sec(x)
  8. Calculate the following definite integrals:
    1. ò02 (x2-1)2 dx
    2. ò01 x[Ö(3-x2)] dx

  9. Compute the area bounded by the curves y = x2-2 and 2x2+x-4.
  10. Compute the volume of revolution about the axis of the curve

    y = x2-2x,     1 £ x £ 2.
