Does anybody know what came first for trigonometric functions?

AI Thread Summary
The discussion focuses on the historical development of trigonometric functions, seeking a timeline and key contributors to their creation. It questions whether the Greeks had knowledge of trigonometric functions and explores the relationship between tangent in calculus and trigonometry. Additionally, it addresses the application of trigonometric functions to right-angled triangles. A recommendation for further reading is provided, specifically a Wikipedia article on the history of trigonometry. Understanding the evolution of these mathematical concepts is essential for grasping their modern applications.

I want a timeline for trigonometric function and how it was developed. Just like who created it and stuff like that. Did the greeks know about trigonometric functions? Is a tangent in calculus the same as a tangent in trigonometry and the function os a trigonometry? How do trigonometric functions apply to right angle triangles?

Thread 'Non-orthogonal bases'

Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...

Thread 'What Exactly is Dirac’s Delta Function? - Insight'

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
