The approximation sign "≈" I use for decimal approximations with tilde "~" being a rougher approximation. Tilde "~" I use to state a geometric shape is similar to another one ie a triangle …

2015年4月30日 · This is why we say $5^6$ and $1$ are "equivalent" under the modulo operation 7. and thats why we use equivalent symbol instead of equality symbol. If you are trying to write …

2017年6月29日 · I suppose similarity is an equivalence relation. $\equiv$ is "equivalent to" and appears in regularly in modular arithmetic. $\approx$ is aproximately. $\cong$ is congruence …

2018年5月20日 · $\begingroup$ $\equiv$ and similar variations are a generic symbols used to notate an equivalence relation. $=$ is the specific equivalence relation "equals" that we are …

2015年5月19日 · $\begingroup$ IMHO, this argument is not very strong as, in the end, everything just follows from the axioms :) The use of $\triangleq$ is meant to improve readability, and can …
