### Textbook corrections

• Logic
• Section 1.2: In Question 22, I put the answers in the wrong order. The number of proper subsets is 2n-1, while the number of subsets is 2n. The .pdfs have been updated.
• Section 1.6: In Questions 23 and 24, the conclusions were correct, but I used the wrong expressions in the truth tables. The .pdfs have been updated.
• Section 1.10: I've added the handwritten solutions to the proofs (numbers 41-49), including the names of the laws for #49. Sorry about that! The .pdfs have been updated.
• Section 1.10: The answer to Question #2 should have had q's in it, not p's. The .pdfs have been updated.
• Section 1.12: The "95%" in Questions #21 and 32 has been changed to "90%" to reflect Camosun's current grading policy (at the time I originally wrote this, 95% was indeed an A+). And I forgot the "let q denote" part in the directions before questions #27 to 30. The .pdfs have been updated.
• Sequences and Series
• Section 3.1: The answer to #37 has been fixed -- the last part should have read an = an-1 + 2n - 1, rather than 2n + 1 as I had before. The .pdf has been updated.
• Section 3.2: There are two places where I had used the equation "an = an + (n - 1)*d", which has been corrected to "an = a1 + (n - 1)*d". The .pdfs have been updated. Many course materials are available in the Adobe Acrobat PDF file format. To read and print PDF files, you will need to install the free Acrobat reader.
