Truth Table Generator. This tool generates truth tables for propositional logic formulas. You can enter logical operators in several different formats. For example, the propositional formula p ∧ q → ¬r could be written as p /\ q -> ~r , as p and q => not r, or as p && q -> !r . The connectives ⊤ and ⊥ can be entered as T and F .A logarithmic function is an inverse of the exponential function.In essence, if a raised to power y gives x, then the logarithm of x with base a is equal to y.In the form of equations, aʸ = x is equivalent to logₐ(x) = y. In other words, the logarithm of x, or logₐ(x), shows what power we need to raise a to (or if x is greater than 1, how many times a needs to be multiplied by itself) to ...Logical Equivalence . If any two propositions are joined up by the phrase "if, and only if", the result is a compound proposition called an equivalence. The two propositions connected in this way are referred to as the left and right side of the equivalence. By asserting the equivalence of two propositions, it is intended to exclude the ...
