- neximo64 5y agoI assume you didn't actually read the article. It is not the QP formula.
- sedeki 5y agoI read the article. It is called "pq formeln" _in Swedish_. The p and q refers to the traditional names of the coefficients. I cannot find any link in English referring to it, but it is part of the standard curriculum. One example of a website explaining it here below (in Swedish), but still, you can clearly see that it's the same formula OP has given: https://eddler.se/lektioner/pq-formeln/ https://eddler.se/lektioner/pq-formeln/
- jonsen 5y agoRight, but this just describes how to use this variant of the more standard formula. What is interesting is how do you derive the formula.
- sedeki 5y agoYup, agreed. But this the standard formula everyone here memorizes, so I thought it might be interesting since it wasn't mentioned anywhere in the article. I did refer to the "result" rather than the derivation.
