Palanikumar Department of Mathematics, SRM Valliammai Engineering College, Kattankulathur, 603203, Tamilnadu, India Omaima alshanqiti Department of Mathematics, Umm al-qura university, Makkah, Saudi Arabia This article presents a new way of analyzing multiple attribute decision-making (MADM) using (♭1, ♭2, ♭3) sin trigonometric complex neutrosophic sets (ST-CNS). Complex neutrosophic weighted averaging (ST-CNWA), sin trigonometric complex neutrosophic weighted geometric (ST-CNWG), sin trigonometric complex generalized neutrosophic weighted averaging (ST-CGNWA), and sin trigonometric complex generalized neutrosophic weighted geometric (ST-CGNWG). During our discussion, we presented an algorithm that utilized these operators. There are extensive numerical illustrations of score values. Furthermore, we will discuss commutativity, idempotency, and monotonicity of sin trigonometric complex neutrosophic sets as part of our discussion. It is easier, faster, and more convenient to find the best option this way. Consequently, the sin trigonometric complex (♭1, ♭2, ♭3) is more closely related to precise conclusions. Also revealed by the study was an intriguing and fascinating observation. 2024 206 223 2579 https://creativecommons.org/licenses/by/4.0/ 10.54216/IJNS.230416 https://www.americaspg.com/journal/21/article/2579 https://www.americaspg.com/storage/81710349379.pdf
