AI Thread Summary
The graphs of y = 2x/3x and y = 2/3x squared are identical on a graphing calculator due to the way the expressions simplify. The expression 2x/3x can be rewritten as (2/3)x, which is equivalent to (2/3)x^2 when evaluated correctly. This demonstrates that both functions yield the same result when plotted. Understanding the order of operations in multiplication and division is key to this equivalence. Thus, both equations represent the same function graphically.

TL;DR Summary
Functions of both graphs are identical on calculator.
On my graphing calculator y = 2x/3x gives precisely the same graph as y = 2/3x squared. How is this possible?

Multiplications and divisions should be evaluated from left to right. 2x/3x = (2x/3) x = (2/3) x^2

If you want the calculator to graph ##y = \frac{2x}{3x}##, write it as y = (2x)/(3x)

Thanks. Much appreciated.
 
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...
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...
