AI Thread Summary
Azis is constructing two cones with specific relationships between their dimensions. The surface area of the first cone is twice that of the second, and its side length is also double. The equations derived from these relationships lead to a ratio of the radii, suggesting that r1 is four times r2. However, the base area must also be considered to finalize the ratio. The discussion emphasizes the importance of quadratic equations in solving for the radius ratio of the cones.

Azis wants to make two cones using cartons. The surface area of the first cone is twice the second. The side length of the first cone is also twice the second. Determine the ratio of those cones' radius!

s1 = 2s2
L1 = 2L2
πr1(r1 + s1) = 2πr2(r2 + s2)
r1(r1 + 2s2) = 2r2(r2 + s2)

I was stuck with quadratic equations...

$A_1 = 2A_2 \implies \pi r_1 \cdot L_1 = 2\pi r_2 \cdot L_2 \implies \pi r_1 \cdot L_1 = 2\pi r_2 \cdot 2L_1 \implies \dfrac{r_1}{r_2} = 4$
 
But we must take into account the base area...
 
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...
