AI Thread Summary
The discussion focuses on solving the function g(x) = (kx - p)/2, given g(7) = 8 and g(5) = 5, prompting the need to find values for k and p rather than x. Participants emphasize the importance of showing work to facilitate better assistance. Additionally, there is a request to clarify the concept of an "onto function" in relation to the function f(x) = x + 1. The conversation highlights the need for deeper understanding and clear communication in mathematical problem-solving. Overall, the thread encourages collaborative learning through shared progress and definitions.

1) If g(x) = \frac{kx-p}{2} , g(7) = 8 , g(5) = 5 then find the value of x and g(x) .
2 )Show that f : N \implies N and f(x) = x+1 is onto function .

We ask that our users show their progress (work thus far or thoughts on how to begin) when posting questions. This way our helpers can see where you are stuck or may be going astray and will be able to post the best help possible without potentially making a suggestion which you have already tried, which would waste your time and that of the helper.

Can you post what you have done so far?

? x has values 5 and 7 and the corresponding values of g(x) are 5 and 8. You are GIVEN that! A more reasonable problem would be to find the values of k and p.

2 )Show that f : N \implies N and f(x) = x+1 is onto function .

Do you know what "onto function" means? What is the definition?
 

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...
