Given the semi-major axis and a flattening factor, is it possible to calculate the semi-minor axis?	Yes, you can calculate the semi-minor axis of an ellipse if you have the semi-major axis and the flattening factor. The flattening factor \( f \) of an ellipse is defined as: \[ f = \frac{a - b}{a} \] where: - \( a \) is the semi-major axis, - \( b \) is the semi-minor axis.

I just came back from my Number Theory course, and during the lecture there was mention of the Collatz Conjecture. I'm sure that everyone here is familiar with it; it describes an operation on a natural number – $n/2$ if it is even, $3n+1$ if it is odd. The conjecture states that if this operation is repeated, all numb...	Your discussion touches on an interesting aspect of mathematics: the conjectures that were initially believed to be true and then later found to be false due to counterexamples. While Polya's conjecture is indeed one such case, there are several other well-known conjectures that have been disproven by counterexamples. ...	107	[ { "from": "human", "value": "I just came back from my Number Theory course, and during the lecture there was mention of the Collatz Conjecture.\nI'm sure that everyone here is familiar with it; it describes an operation on a natural number – $n/2$ if it is even, $3n+1$ if it is odd.\nThe conjecture states t...
This is such a basic question I'm sure, but I've been trying to find a robust solution to it for a while. Lets say I have the numbers 0-100 in series. As the number increases, I want another number say 1000, to decrease. so that when you got to 100, it was at 0 0 = 1000 50 = 500 100 = 0 What is this kind of series call...	What you're describing is a linear relationship where one variable decreases as another variable increases. Specifically, in your case, you have two variables: 1. X: The numbers from 0 to 100. 2. Y: The corresponding values that start at 1000 and decrease to 0 as X increases from 0 to 100. The relationshi...	931	[ { "from": "human", "value": "This is such a basic question I'm sure, but I've been trying to find a robust solution to it for a while.\nLets say I have the numbers 0-100 in series.\nAs the number increases, I want another number say 1000, to decrease. so that when you got to 100, it was at 0\n0 = 1000\n50 =...
