Rhea Section for MA375 Professor Walther, Fall 2015

This page refers to the "Lecture Notes in Discrete Mathematics" of MA 375 in Fall of 2015, by Uli Walther.

To edit: click on "user" and choose "log in" in the drop down menu. Enter Purdue ID and password. After logging in, click "actions" and select "edit". Then make the requisite changes in the editor you will see. Then click "save page" all the way down. Check that you wrote what you wanted.

Do not delete or edit previously listed typos.

Please list any typo found in the course notes below. Mimic the first two entries: indicate page, line from above (positive numbers) or from the bottom (negative numbers), old text and new text. Add a new line for each typo.

  • 1. page 3, line -5, "Week 5" should be omitted.
  • 2. page 4, line 8, "Week 7" should be omitted.
  • 3. page 9, line -2, {Hx2} should be {H2}.
  • 4. page 14, line 6, R| should be |R|.
  • 5. page 15, line 23, |A and B and C| should be |A or B or C|.
  • 6. page 11, line 13, n! should be n.
  • 7. page 11: Exercise 1.8 Question Number 10: The question does not say what set the equation is under. I assume that the set is under all natural numbers greater than or equal to 1 since excluding the numbers and just looking at 2n-1=n^2 if 0 is inserted it makes the equation -1=0 which is not true.
  • 8. page 28, line -1, x = 79*l should be x = 7+9*l.
  • 9. page 29, line -13, x = r*i*b - s*j*a should be x = r*i*b + s*j*a.
  • 10. page 31, line 12, p*(a-1) should be a*(p-1).
  • 11. page 45,line 12, the question says find the total of amount of..., The first "of" should be omitted
  • etc.
