AI Thread Summary
Negative numbers squared can appear as negative on calculators due to the order of operations. When inputting -1^2, calculators interpret it as -(1^2), resulting in -1. To correctly square a negative number, it should be entered as (-1)^2, which yields the expected result of 1. This highlights the importance of parentheses in mathematical expressions. Understanding this can help avoid confusion when using calculators.

Why do negative numbers which are squared by a even number always return as a negative while using a calculator? e.g. (-1)^2 = 1, except calculators say -1, even though -1*-1 = 1 :S:S

Well, if you type it in like this: -1^2 then the calculator interprets it as -(1^2)=-1. try inputting (-1)^2.
 
Oh okay, thanks.
 

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...

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...
