The equation of a a quadratic function can be determined from a graph showing the turning point and another point on the graph. Brush up on your knowledge on how to recognise and determine the ...

Revise how to recognise and determine the equation of a quadratic function from its graph. BBC Bitesize Scotland revision for SQA National 5 Maths.

This brief deals with introducing some simple algebraic conditions ensuring the positive realness of a biproper rational function. By meeting these conditions, which specify inequality-based criteria ...

In this chapter, the authors describe the rational function fitting method (RFFM) and spectral differential equation approximation method (SDEAM), which shift the burden of numerical computations from ...

A spectral scheme using the modified Legendre rational functions for the Korteweg-de Vries equation on the half line is investigated. The numerical solution of the scheme is shown to possess the ...

Abstract Recently we have reported a new method of rational approximation of the sinc function obtained by sampling and the Fourier transforms. However, this method requires a trigonometric multiplier ...
