AI Thread Summary
The equation xy = x/y = x - y is presented for analysis, with the condition that y cannot equal 0. The solution reveals that x is -1/2 and y is -1, which satisfies the equation. By verifying the calculations, it shows that y can be either +1 or -1, confirming the results. The discussion concludes with a successful resolution of the problem. The solution demonstrates that the values of x and y are consistent across the given equations.

One of my friends asked me this, and I have no idea how to get the answer. I don't even know if there is an answer... if someone could help, that'd be great:

xy = x/y = x-y

If y cannot equal 0, what is the value of x and y?

Thanks :D

Unless I goofed in the calculation, x is -1/2 and y is -1. Work out xy = x/y to see that y is either +1 or -1, then work out the subtraction.
 
Wow, it works! Thanks =)
 
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...
