AI Thread Summary
A function is a relationship between inputs and outputs where each input is related to exactly one output. An equation is a mathematical statement that asserts the equality of two expressions, often containing variables. A formula is a specific type of equation that expresses a relationship between different quantities, typically used for calculations. The distinctions lie in their definitions and applications: functions describe relationships, equations assert equality, and formulas provide a method for computation. Understanding these differences is essential for grasping fundamental mathematical concepts.

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...
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...
