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
- 12. page 38, question 3.21, The question seems misworded in that it can be thought to mean if the intersection of E1 and E2 are independent of F rather than finding out if each one is independent of F. I would recommend breaking this question into subparts.
- 13. page 41, line 19, "Iphone" either has the wrong capitalization or has an extra "I". It should read either "phone" or "iPhone".
- 14. page 45, line 12, "amount of inversions" should read "number of inversions".
- 15. page 37, line 8, u'(y) dy) should be u'(y) dy (parenthesis typo).
- 16. page 39, line 7, p(e) should be p(E).
- 17. page 39, line -7, if an only if should be if and only if.
- 18. page 40, line 6, ambiguous expression: sqrt(3)/2*r should be r*sqrt(3)/2, like in the next line.
- 19. page 40, line 7, sqrt(2)/3 should be sqrt(3)/2.
- 20. page 40, line -18, should on should be should not.
- 21. page 40, line -16, unformly should be uniformly.
- 22. page 49, line 3, It says "The setup it", but it should say "The setup is"
- 23. page 40, line 20, f(g(y) should be f(g(y))
- 24. page 61, line -14, this paragraph should be indented.
- 25. page 61, line -16, this paragraph should be indented.
- 26. page 61, line -8, "(2,2) These" should be "(2,2). These"
- 27. page 49, exercise 4.4 (4) "......exactly the same number of acquaintances in the audience?" should be "....exactly the same number of acquaintances in the attendance?"
- 28. page 56, line -19, {(1,2,3)} should be {1,2,3}.
- 29. page 56, line 11, change actual should be actual change.
- 30. page 57, line 14, imaging should be imagine.
- 31. page 70, line 6, an+1 should be an-1.
- etc.
