construct a rational function?
Hello, my task is to construct a non-constant rational function r : R → R with 2 ≤ r(x) ≤ 3 for all x ∈ R. Unfortunately, I have no idea how to go about this. Does anyone have any ideas?
Mathematical proof?
Hello! What methods are there to determine whether a natural number is a square number? I don't mean taking square roots or anything like that. For example, for a number with a special pattern (it doesn't have to be; it can also be a completely normal number), is there a mathematical theorem to show that…
How to determine all x from the real numbers?
Hello, I'm supposed to determine all x's from the real numbers in this equation. I'm stuck at the bottom step and don't know what to do next. I'd actually like to factor out the factors and then continue calculating using log. Were my calculations correct up to this point, and how do I get the…
Calculate complex numbers?
I'm currently stuck on the last subtask. Do you have any ideas for an approach?
From what number does every number always have 3 divisors where no fractions arise?
Is there a number from which every number has 3 divisors and no number only 2 divisors, for example the number 7 has only 2 divisors, the number 8 has 4 divisors but the number 11 again only 2 divisors? Is there then a number from which all numbers have 4 divisors, etc.
Instagram Reels?
I have a private Instagram account with about 350 followers. Why is the number of my videos being viewed increasing? I get a notification saying "Your video has been played 700 times." Can't understand how this number is formed
