Definite integrals are a fundamental concept in calculus, allowing us to compute the area under a curve on a given interval. In this article, we will explore the process of calculating definite ...

Abstract: Intuitionistic fuzzy numbers (IFNs) are the basic components of Atanassov's intuitionistic fuzzy sets, which are very convenient and comprehensive in depicting the fuzzy characters of things ...

Abstract: Intuitionistic fuzzy set (A-IFS) introduced by Atanassov, a generalized form of fuzzy sets, is a useful tool to deal with vagueness and ambiguity. Each element of an A-IFS is called an ...

Brush up on your knowledge of using integration to calculate definite integrals for the Higher Maths exam.

GAUSS, I believe, gave a very large number of forms for approximate evaluation of definite integrals between finite limits. His formulæ are all based, like Tehebycheff's rules, on the assumption that ...
