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… WebDec 30, 2015 · test.txt. Taking derivative of discrete data requires some fitting and then using the b-form of the polynomial. How to make a 'good' fit and properly take derivative?

WebThe mean of X can be found by evaluating the first derivative of the moment-generating function at t = 0. That is: μ = E ( X) = M ′ ( 0) The variance of X can be found by evaluating the first and second derivatives of the moment-generating function at t = 0. That is: σ 2 = E ( X 2) − [ E ( X)] 2 = M ″ ( 0) − [ M ′ ( 0)] 2 WebDiscrete functions have differences or divided differences and not derivatives. For example if f (n) = 2n^3 + 7n then the first forward difference is f (n+1) - f (n) and the first backward difference is f (n) - f (n-1). These are 2 (n+1)^3 - 2n^3 + 7 (n+1) - 7n = 6n^2 + 6n + 9 and 2n^3 - 2 (n-1)^3 + 7n - 7 (n-1). impacts of cyberattacks

WebIn mathematics, function derivatives are often used to model these changes. However, in practice the function may not be explicitly known, or the function may be implicitly represented by a set of data points. In these cases and others, it may be desirable to compute derivatives numerically rather than analytically.

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.
