Advanced Calculus Single Variable

2.2 Exercises

  1. Consider the expression x + y
    − x
    ≡ f
    . Find f
    .
  2. Show −
    =
    b.
  3. Show on the number line the effect of multiplying a number by −1.
  4. Add the fractions
    +
    .
  5. Find a formula for
    2,
    3, and
    4. Based on what you observe for these, give a formula for
    8.
  6. When is it true that
    n = xn + yn?
  7. Find the error in the following argument. Let x = y = 1. Then xy = y2 and so xy −x2 = y2 −x2. Therefore, x
    =
    . Dividing both sides by
    yields x = x + y. Now substituting in what these variables equal yields 1 = 1 + 1.
  8. Find the error in the following argument.
    = x + 1 and so letting x = 2,
    = 3. Therefore, 5 = 9.
  9. Find the error in the following. Let x = 1 and y = 2. Then
    =
    =
    +
    = 1 +
    =
    . Then cross multiplying, yields 2 = 9.
  10. Find the error in the following argument. Let x = 3 and y = 1. Then 1 = 3 − 2 = 3 −
    = x − y
    =
    = 22 = 4.
  11. Find the error in the following.

    Now let x = 2 and y = 2 to obtain

  12. Show the rational numbers satisfy the field axioms. You may assume the associative, commutative, and distributive laws hold for the integers.
