x,y / x,y = <z Please Register or Log in to view the hidden image! This should be an interesting question for you mathematicians !
This makes no sense! If x,y is intended to denote a point in the X,Y plane ( equivalent to the vector space \(R^2\)) then it is a vector. Vectors add, have additive inverses (which gives you a kind of "subtraction") but they do not multiply (and therefore do not divide). It's a definition, live with it.
x,y a circular plane x,y / x,y is an expansion of that plane <z equals the contraction of z why x,y is expanding. Have you never heard of centrifugal force contacting a spherical shape and making it oblate ? Want to try again with the sense part ? Please Register or Log in to view the hidden image!
There is no such thing as a "circular plane". A disk, if that is what you mean, is a subset of the 2-plane \(R^2\) The rest is gibberish No thanks
I'm no mathematician but my understanding is that a plane is infinite in all directions and therefore can have no shape and also can not expand.
There is no such thing as a x,y plane but you recognised I was explaining a disk . Do I sense a bit of arrogance from you ? You understood a x,y plane is a disk so I disagree with your attempt to undermine me by word use.
Not true or they wouldn't call an aeroplane an aeroplane. A plane can be a finite or an infinite plane . Horizontal or vertical planes are just flat in meaning such as a disk , a x,y plane .
That's English, not mathematics. Wikipedia disagrees: https://en.wikipedia.org/wiki/Plane_(geometry) "In mathematics, a plane is a flat, two-dimensionalsurface that extends infinitely far."
WIKI is inaccurate , to state a plane is infinite when we have not yet established an infinite universe is a false claim . Additionally a plane just means flat such as a x,y disk .
Don't confuse mathematics with reality. Mathematics is pretty good at describing reality but it can also go beyond reality. (After all, we don't know what reality is going to look like as new information is added, so we need a flexible system to describe it.) Mathematically, a plane is infinite.
I wouldn't be stupid enough to dabble in explosives , I'd probably blow myself up and that wouldn't be very bright.
It is not true. As sideshowbob points out, objects in mathematics are unconstrained by the real world. I can manipulate an object a quadrillion light years on a side in a mathematical plane like it was child's play. It is telling about your mathematical prowess that you are unaware of this.
Interstella: it's great that you're interested and inquisitive about math and physics. We live for your kind of enthusiasm. And we don't want to squash it. But you don't know what you don't know. You must study. How far is the nearest library? Find some books and basic physics and math and get reading.
