Formulae with connectives
Definitions
Read the section of truth tables from the textbook material on connectives.
Computing the truth value of a complex formula
Note: This is copied from the textbook material on connectives.
Preparing for week 4: Connectives
The following video presents the step-by-step computation of the truth value of two formulae with connectives. The example uses a model based on Shakespeare's play Macbeth. The two formulae are:
- ¬ king(lady-macbeth)
- king(duncan) ∨ king(lady-macbeth)
The next video shows how the truth value of a more complex formula can be computed. The example contains two connectives:
kill(malcom,lady-macbeth) ∨ ¬thane(macbeth)
The video shows two different methods: top down and bottom up.
For next week (May 2)
- Read Levine et al (in prep.), Chapter 2, section 2 (especially 2.2.1 and 2.2.2)
- Using your model from last week,
- Give 2 atomic formulae.
- Give 1 statement with a conjunction ("and")
- Provide the step-by-step computation of the truth of your 3 statements.
