A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics (NEW RULE as of 5 Nov 2024, trying it out)
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct

In calculus, things that divide by zero you really learn ״go to infinity” - just graph it and you’ll see! The smaller the denominator gets the larger the result. True, there is no actual value at actual zero. But isn’t sickness limited death? But my crap is still zero because of the numerator.

Thats incorrect too, the real answer is that its undefined. Infinity only is the correct answer if you only examine it from the positive side, so limit of a/x as x goes to 0 is infinity, but if x starts out as negative, the answer would be negative infitnity, causing a logical paradox.

Notice I never said the value IS infinity. I said it “goes to infinity” which is the mathematically correct way to describe what’s going on when considering the limit, at least on the positive side. Of course, because on the negative side of zero, the function goes to negative infinity, it makes the most sense to describe it as undefined, still. 😉
