Linear algebra
Relations
Given the sets over the domain {a, b, c, d}:
A = { (a, a), (b, b), (d, d), (b, a) }
B = { (a, c), (c, c), (c, a), (d, a) }
C = { (a, c), (a, d), (c, b), (c, c) }
For A, B, and C: find the following closures.
1. Reflexive
2. Symmetric
3. Transitive
Logic
1. Simplify the following using a truth table.
¬( (p ∧ q) -> (p ∨ q))
2. Show if the following is equivalent to ¬ p ∧ ¬ q . Use Boolean math. Label each law that you apply.
¬(p ∨ (¬ p ∧ q))
3. Simply the following using Boolean Math. Label each law that you apply.
b ∧ a ∨ e ∧ c ∧ ¬e ∨ ¬a ∧ b
4. Write out and prove (or disprove) the following statement.
“If I’m sleepy, then I’ll drink coffee or tea. I’ll never drink tea. Therefore, if I’m sleepy, then I'll drink coffee"
Convert the English sentence to an argument (short notation). Then, use a truth table to prove/disprove it:

- PROOF EVALUATION (This type of exercise will appear occasionally): Each of the follow- ing is a proposed "proof" of a "theorem". However the "theorem" may not be a true statement, and even if it is, the "proof" may not really be a proof. You should read each "theorem" and "proof" carefully and decide and state whether or not the "theorem" is true. Then: • 18 If the "theorem" is false, find where the "proof" fails. (There has to be some error.) If the "theorem" is true, decide and state whether or not the "proof" is correct. If it is not correct, find where the "proof" fails.arrow_forwardMathmaticsarrow_forwardHow do you solve this question on discrete mathematics: 2.
