AI Thread Summary
To calculate the distance from a random point inside a circle to N uniformly distributed points, the process is straightforward but can become tedious as N increases. The average distance remains constant regardless of the number of points, while the standard deviation decreases with larger N. This indicates that while the average distance does not change, the distribution of distances becomes more consistent. Understanding these dynamics is crucial for applications involving spatial analysis within circular areas. The discussion highlights the mathematical principles governing distance calculations in geometric contexts.

How can I calculate the distance from a random point IN a circle to N points uniformly distributed within the circle? Would the average distance decrease with N?

If the coordinates of the random point and the N points are given, the calculation is simple, but tedious for large N.

The average distance (for a fixed initial point) would not change with increasing N, although the standard deviation would get smaller.
 
Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...
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 'Imaginary Pythagorus'
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...
