Neutrosophic normal vague set fitting to trigonometric concept via aggregation operators and its augmentation

Abstract

Using a cotangent trigonometric neutrosophic normal vague set (CotNNVS), we begin this com-munication article with several novel techniques. Some trigonometric neutrosophic sets and imprecise neutro-sophic sets are extended by the novel idea of CotNNVS. We will discuss the various aggregating processes that interpret Cotangent trigonometric neutrosophic normal vague weighted averaging (CotNNVWA), cotangent trigonometric neutrosophic normal vague weighted geometric (CotNNVWG), cotangent trigonometric generalized neutrosophic normal vague weighted averaging (CotGNNVWA), and cotangent trigonometric generalized neutrosophic normal vague weighted geometric (CotGNNVWG) are the new topics covered in this paper. © 2025, University of New Mexico.
