Two logical formulas p and q are logically equivalent, denoted p ≡ q, (defined in section 2.2) if and only if p ⇔ q is a tautology. We are not saying that p is equal to q. Since p and q represent two different statements, they cannot be the same. What we are saying is, they always produce the same truth value, regardless of the truth values ...The Fine Structure Constant Alpha = 1/2 (e/Q)^2 = 7.2E-3 where 'e' is the electric charge and Q the quantum charge.

See full answer below.TL;DR (Too Long; Didn't Read) On a calculator display, E (or e) stands for exponent of 10, and it's always followed by another number, which is the value of the exponent. For example, a calculator would show the number 2.5 trillion as either 2.5E12 or 2.5e12. In other words, E (or e) is a short form for scientific notation.Composition of Functions. In addition to adding, subtracting, multplying and dividing, two functions can be composed. The composition of a function is when the x-value is replaced by a function. For example if p (x) = x 3 and q (x) = x - 1, the compostition of p with q is: The notation p ∘ q, reads "p composed with q".What does Q mean in mathematics? rational numbersList of Mathematical Symbols. • R = real numbers, Z = integers, N=natural numbers, Q = rational numbers, P = irrational numbers.
