Want facts and want them fast? Our Maths in a minute series explores key mathematical concepts in just a few words.
The COVID-19 pandemic has amplified the differences between us. Understanding these inequalities is crucial for this and future pandemics.
Now it's the turn of mathematicians to help to improve the communities of the future.
There have been accusations that the modelling projecting the course of the pandemic was too pessimistic. Are they justified?
We all know what turbulence is, but nobody understands it.
Find out about the beautifully intuitive concept that lies at the heart of calculus.
Firstly, that's an odd use of the term 'reverse' when talking about mathematical functions. At any rate, your table of values doesn't even follow from your definition of the function F.
To get F(-1) = 0, I presume you decided to 'invert' the operator, which would make F(-2) = (-2) ÷ [(-2) - (-2)] = -2 ÷ 0, which is undefined (not infinity). Since all subsequent terms will end with a (-x) - (-x) in a denominator, they are ALL undefined.
That being said, I think you have the beginning of an intriguing idea: the *down* arrow for repeated division.
