Delta Function from Wolfram MathWorld The delta function is a generalized function that can be defined as the limit of a class of delta sequences The delta function is sometimes called Dirac s delta function or the impulse symbol Bracewell It is implemented in the Wolfram Language as DiracDelta x. Dirac delta function video Khan Academy Feb , Your Dirac delta function is a function of t, and because of this, if you ask what s the limit as tau approaches zero of the integral from minus infinity to infinity of d sub tau of t dt, well, this should still be , right The Delta Function by Rosa Montero Translated into English by Kari Easton and Yolanda Molina Gaviln, The Delta Function explores a woman s fears of being abandoned, of being alone, and of dying A unique double narrative structure throws into relief time s effect on her self identity, sexuality, and relations with others. Delta Function Dirac Delta Function Generalized PDF Using delta functions will allow us to define the PDF for discrete and mixed random variables Thus, it allows us to unify the theory of discrete, continuous, and mixed random variables Dirac Delta Function Remember, we cannot define the PDF for a discrete random variable because its CDF has jumps. The Delta Function The Scientist and Engineer s Guide to The delta function is a mathematical construct, not a real world signal Signals in the real world that act as delta functions will always have a finite duration and amplitude Just as in the discrete case, the continuous delta function is given the mathematical symbol . How to use the Excel DELTA function Exceljet The Excel DELTA function will test if two numeric values are equal When values are equal, DELTA returns , otherwise, DELTA returns zero Purpose Test two values are equal Return value The number one or zero Syntax DELTA number, number Arguments number The first number. The Delta Function European Women Writers Paperback Translated into English by Kari Easton and Yolanda Molina Gaviln, The Delta Function explores a woman s fears of being abandoned, of being alone, and of dying A unique double narrative structure throws into relief time s effect on her self identity, sexuality, and relations with others.

I risked myself to read this author translated to English because I feel that her writings are so good that I would understand and -more important- enjoy the story. And I was not wrong: I loved this story about a woman that is dying in a hospital; and remembers a very important week of her life. It is a wonderful story.

"Es una función que describe fenómenos discontinuos de gran intensidad, pero brevísima duración. O sea, fenómenos cuya intensidad tiende al infinito y cuya duración tiende a cero. Si se pudiera visualizar sería como una línea quebrada - y diciendo esto dibujaba con su mano el perfil de una sierra en e espeso olor a siesta- de ángulos agudísimos, ¿me entiendes?"
