معادلات تابعی معادلاتی هستند که مجهول در آن ها به شکل تابع است. مشهورترین معادلات تابعی معادله تابعی کشی یعنی f(x+y)=f(x)+f(y) است که یکی از توابع صادق در این معادله f(x)=x است. هم چنین معادله تابعی مربعی f(x+y)+f(x-y)=2f(x)+2f(y) که یکی از جواب های آن تابع مربعی f(x)=x^2 است. سوال مهمی که در این جا مطرح است این است که، اگر تابعی تقریبا در یک معادله تابعی صدق کند، آیا به یک جواب آن معادله تابعی...
In this article, we apply the Daftardar-Gejji and Jafari method (DJM) to solve multispecies Lotka–Volterra equation. A comparison between DJM, differential transformation (DTM), variational iteration (VIM), Adomian decomposition (ADM) shows that DJM is a reliable powerful for solving nonlinear equations. The efficiency applicability of are confirmed by considering some examples. proposed proced...
in the area of vocabulary teaching and learning although much research has been done, only some of it has led to effective techniques of vocabulary teaching and many language learners still have problem learning vocabulary. the urge behind this study was to investigate three methods of teaching words. the first one was teaching words in context based on a traditional method of teaching that is,...

Abstract The current paper is about the investigation of a new integral transform introduced recently by Jafari. Specifically, we explore applicability this on Atangana–Baleanu derivative and associated fractional integral. It shown that applying specific conditions transform, other transforms are deduced. We provide examples to reinforce transform.
It is widely recognized that mathematically simple systems of nonlinear differential equations can exhibit chaos. With the advent of fast computers, it is now possible to explore the entire parameter space of these systems with the goal of finding parameters that result in some desired characteristics of the system. Recently there has been increasing attention to some unusual examples of such s...
abstract sensitive and precise voltammetric methods for the determination of trace amounts of furaldehydes, mainly as furfural (f) and 5-hydroxymethyl-2-furaldehyde (hmf), in waste waters and other matrices is described. determination of total furaldehyde at < ?g g-1 levels in alkaline buffered aqueous media was individually investigated. by the use of ordinary swv and adsorptive square wave ...
