Derivative of discrete function

Discrete differential calculus is the study of the definition, properties, and applications of the difference quotient of a function. The process of finding the difference quotient is called differentiation. Given a function defined at several points of the real line, the difference quotient at that point is a way of encoding the small-scale (i.e., from the point to the next) behavior of the function. By fin… WebMost methods derive from the basic derivation of differentiation of a function f(t): ( ) ( ) t f t t f t t f f t δ δ δ + − ′ = = →0 lim d d.

http://mathforcollege.com/nm/mws/com/02dif/mws_com_dif_txt_discrete.pdf WebThe orthonormal discrete Legendre polynomials are introduced as suitable family of basis functions to find the solution of these equations. An operational matrix is derived for fractional derivative of these polynomials. A collocation method based on the expressed polynomials and their operational matrices is developed for solving such problems. WebWhat are derivatives? The derivative is an important tool in calculus that represents an infinitesimal change in a function with respect to one of its variables. Given a function f (x) f ( x), there are many ways to denote the derivative of f f with respect to x x. The most common ways are df dx d f d x and f ′(x) f ′ ( x). how are portable tables made
