WebAug 19, 2015 · A wavefunction with negative sign works just like any other wave with negative sign. For example, water waves with negative height cancel out with waves of positive height. You can also make a 'negative' wave on a string by pulling the end down and back up, which will cancel with a positive wave.

WebDiscrete probability distribution function. Mathematically, a discrete probability distribution function can be defined as a function p (x) that satisfies the following properties: 1. The probability that x can take a specific value is p (x). That is. P (X = x) = p (x) = px. 2. p (x) is non-negative for all real x. 3. WebThe function can be extended to negative non-integer real numbers and to complex numbers as long as the real part is greater than or equal ... For more information, see gamma function ...
