So it’s just a matter of definition.
That's what I've said several times. The teacher has a definition of "formula". AloneAgainstAll has another definition in mind and concludes that his teacher was wrong, and is so bad that he wouldn't recommend her to his enemies. I found that judgment too hard.
Yes, you can make such a definition of formula that makes my "formula" not a formula anymore. I heard once from another teacher that 0 is not and odd number and not pair number. Its special number. Yeah, you can define pair numbers and odd numbers in such a way that 0 will not be not pair, nor odd. I used definition of formula that is generally accepted in mathemathics world. I even gave function, and if you go back to 2nd page you will see that this teacher denied existence of function (well, you too) :
This is qoute from you:
"The fact that "there is no formula for producing n-th prime number [f(n)=n-th prime number]" is correct, but the teacher could have said that f(n) ~ n log(n), maybe this would have fascinated part of his audience."
Its not a matter of life to be always right, sometimes you can be wrong. Me too.
Edit:
Some funny (and bit scary) story with a point:
In 1st year of elementary school teacher asked pupils to make drawing, topic : "my family after 100 years". One of childrens draw graves of his parents. Imagine that parents were asked to meet teacher, cuz teacher had suspicions that there might be something wrong with a child. Logic not always pays off in this world.
