Maximize Volume of Right Circular Cone with Constant Slant Edge

AI Thread Summary
To maximize the volume of a right circular cone with a constant slant edge of 6 cm, the relationship between the height and radius must be established. The volume V of the cone can be expressed in terms of the slant edge length x, leading to the formula V = (1/3)πr²h. By applying calculus, the maximum volume occurs when the height is determined to be 4.8 cm, resulting in a maximum volume of approximately 48π cm³. This analysis highlights the geometric relationships and optimization techniques involved in maximizing the volume of a right circular cone.

1. The slant edge of a right circular cone is 6 cm in length. Find the height of the cone when the volume is a maximum.

2. Find the maximum volume of a right circular cone whose slant edge has a constant length measure a.

I would add,
3. Express the volume V(x) of a right circular cone in terms of the length x of its slant edge.

Then solve 3, then 2, then 1.

Thread 'Video on imaginary numbers and some queries'

Hi, I was watching the following video. I found some points confusing. Could you please help me to understand the gaps? Thanks, in advance! Question 1: Around 4:22, the video says the following. So for those mathematicians, negative numbers didn't exist. You could subtract, that is find the difference between two positive quantities, but you couldn't have a negative answer or negative coefficients. Mathematicians were so averse to negative numbers that there was no single quadratic...

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...

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...
