Curiosity about infinity in geometry(Not homework just curious)

AI Thread Summary
The discussion centers on the implications of using area and volume formulas for shapes derived from an infinitely long line segment. Participants explore whether applying these formulas would yield infinitely large shapes, questioning the outcomes for various geometric figures including rectangles, triangles, and circles for area, and spheres, prisms, and cones for volume. The conversation highlights the complexity of defining dimensions and limits in geometry when dealing with infinity. The consensus leans towards the idea that an infinitely long line segment could indeed lead to infinitely large shapes, although the exact nature of these shapes remains uncertain. This exploration raises intriguing questions about the relationship between geometry and the concept of infinity.

Okay, let's say you have an infinitely long line segment.

Using area and volume formulas for different shapes, would you get an infinitely large shape that the formula was for in the first place?
Area:
For rectangles, would you get an infinitely large rectangle with A = l * w?
What about triangles with 1/2 * b * h?
What about squares with l^2
what about rombi with A = b * h?
what about trapezoids with A = ((b1 + b2)*h)/2?
what about pentagons with A = 5/2 * l * a(apothem)?
hexagons with A = (3√3 s2)/ 2?
what about other regular polygons with Area = (a(apothem) x p(perimeter))/2?
what about ellipses with π * vertical radius * horizontal radius?
What about circles with π * r^2
Volume:
What about spheres with V = ⁴⁄₃πr³?
What about triangular prisms with 1/2 x b x h x l?
what about other prisms with V = area of base * l (yes that includes the cylinder at the infinite end)?
what about dodecahedrons with (15+7×√5)/4 × (Edge Length)^3
what about octahedrons with (√2)/3 × (Edge Length)^3
what about Icosahedrons with 5×(3+√5)/12 × (Edge Length)^3
What about toruses that have holes with 2 × π^2 × R(radius of hole) × r^2(radius of circular cross section)?
What about cones with π × r^2 × (h/3)?

What do you think?
 
I think that you would get an infinitely large shape from an infinitely long line segment but I honestly don't know.
 
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...
Thread 'Imaginary Pythagoras'
I posted this in the Lame Math thread, but it's got me thinking. Is there any validity to this? Or is it really just a mathematical trick? Naively, I see that i2 + plus 12 does equal zero2. But does this have a meaning? I know one can treat the imaginary number line as just another axis like the reals, but does that mean this does represent a triangle in the complex plane with a hypotenuse of length zero? Ibix offered a rendering of the diagram using what I assume is matrix* notation...
