Note: the solutions to most of the multiple choice questions in these sections use what call the standard assignment of truth values to atomic propositions. The standard assignment of truth values assigns the values given here to the variables in the wffs in the exercises, when read left to right. So, the first variable in the formula read left to right gets the α assignment; the second variable in the formula read left to right (if any) gets the β assignment; the third variable in the formula read left to right (if any) gets the γ assignment; and the fourth variable in the formula read left to right (if any) gets the δ assignment.
For exercises with only one propositional variable, the standard assignment is:
For exercises with two propositional variables, the standard assignment is:
For exercises with three propositional variables, the standard assignment is:
For exercises with four propositional variables, the standard assignment is:
For each of the given propositions, determine which of the given sequences properly describes the column under the main operator, given the standard assignment of truth values to atomic propositions.
-(V ? W) • (V ? ?W)
20 Feet
A measure of length equivalent to approximately 6.096 meters, often used in reference to distance or the dimensions of objects.
Sensory Adaptation
The adjustment of sensory receptors to continuous stimulation, leading to decreased sensitivity to that stimulus over time.
Unchanging Levels
A state or condition where there is no variation, fluctuation, or progression in intensity, degree, or quality over a certain period.
Longest Wavelength
Refers to the type of electromagnetic wave that has the lowest frequency and, consequently, the longest wavelength in the spectrum.
