Logical Connectives

2-18-2020 Logical ConnectivesMathematics works according to the laws of logic, which specify how to make valid deductions. In orderto apply the laws of logic to mathematical statements, you need to understand theirlogical you take a course in mathematical logic, you will see a formal discussion of proofs. You start with aformal language, which describes the symbols you re allowed to use and how to combinethem, andrulesof inference, which describe the valid ways of making steps in a proof. Everythingis symbols! If I did thathere you would probably find it hard to follow.

The order of precedence of the logical connectives is: 1. Negation 2. Conjunction 3. Disjunction 4. Implication 5. Double implication As usual, parentheses override the other precedence rules. In most cases, it’s best for the sake of clarity to use parentheses even if they aren’t required by the precedence rules. For example, it’s better ...

A statement in sentential logic is built from simple statements using the logical connectives ¬, ∧, ∨, →, and ↔. The truth or falsity of a statement built with these connective depends on the truth or falsity of its components. For example, the compound statement P → (Q∨ ¬R) is built using the logical connectives →, ∨, and ¬.

divisible by 4, but n = 6 is not divisible by 4. Thus, n = 6 is a counterexample to the statement. On the other hand, consider n = 5. While n = 5 is not divisible by 4, n2 = 25 is also not divisible by 4. For n = 5, the “if” and “then” parts of the statement are both false. Therefore, n = 5 is not a counterexample to the statement. Example.

The Null Space of a Matrix

sites.millersville.edu

The null space is the same as the solution space of the system of equations Ax= 0. I showed earlier that if Ais an m× nmatrix, then the solution space is a subspace of Fn. Thus, the null space of a matrix is a subspace of Fn. Example. Consider the real matrix A= 3 −1 1 −1 1 1 .
