Hace 3 días · A function f from a set X to a set Y is an assignment of one element of Y to each element of X. The set X is called the domain of the function and the set Y is called the codomain of the function.
Hace 4 días · A Fourier series (/ ˈ f ʊr i eɪ,-i ər /) is an expansion of a periodic function into a sum of trigonometric functions. The Fourier series is an example of a trigonometric series, but not all trigonometric series are Fourier series.

The beta function (also known as Euler's integral of the first kind) is important in calculus and analysis due to its close connection to the gamma function, which is itself a generalization of the factorial function. Many complex integrals can be reduced to expressions involving the beta function. Definition. Symmetry. Relation with Gamma Function
19 de may. de 2024 · To roughly estimate the locations of the roots of the equation \( f(x) =0 \) over the interval [a,b], it make sense to make a uniform partition of the interval by sample points \( \left( x_n , y_n = f(x_n )\right) \) and use the following criteria:
Hace 5 días · Second Order Optimal Runge-Kutta Approximation. Ralston's method is a second-order method with two stages and a minimum local error bound. Its Mathematica realization is presented below when the step size is denoted by h: yn + 1 = yn + h 4f(xn, yn) + 3h 4 f(xn + 2h 3, yn + 2h 3 f(xn, yn)), n = 0, 1, 2, ….
