The problem asks you to find $$\lfloor 0.785\rfloor$$. The definition of $$\lfloor x\rfloor$$ for an arbitrary real $x$ is given in the first paragraph of the problem. If you don't understand that definition, I suggest an exchange. You give a detailed explanation of what you do and don't understand in that sentence. This helps me understand what parts of explanations may not be clear, and helps me hopefully explain things better in the future. In exchange, I describe the confusing parts. (I am not the author of the problem, of course.)
 
This is confusing! Yazan975 thanked Evgeny Makarov for his response but did not answer any of the questions or do any of the things that Evgeny Makarov suggested!
 

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...

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...
