Sept. 9 (UPI) --Google is celebrating the start of the 2025-26 school year with a quadratic equation-themed Doodle. The mathematical formula has useful applications across physics, engineering and ...

Abstract: This paper develops a quadratic function convex approximation approach to deal with the negative definite problem of the quadratic function induced by stability analysis of linear systems ...

Abstract: To obtain chaotic systems with good properties to help chaos based image encryption, this paper first study the condition under which quadratic functions can be used as pseudo-random ...

Among the most powerful tools we have as programmers—perhaps the most powerful tools—are functions. We’ve already seen some built-in Python functions, for example, print() and type(). We’ll see many ...

We are concerning with two analytical methods; the classical method of successive approximations (Picard method) [14] which consists the construction of a sequence of functions such that the limit of ...

In mathematics there should be objects called regular and those called irregular (the other opposite part). We have studied regular objects e.g. regular functions like \(y=3x+2\)but at the same time ...

This is a preview. Log in through your library . Abstract It is shown that for wave functions of the form Ψ = Σk Ck exp (-Qk), where Qk is any positive definite quadratic form in the Cartesian ...

Quadratic functions are essential in the world of mathematics and have a wide range of applications in various fields, such as physics, engineering, and finance. An inverse function can be thought of ...
