In mathematical notation, what are the usage differences between the various approximately-equal signs "≈", "≃", and "≅"? The Unicode standard lists all of them inside the Mathematical Operators B...

Feb 14, 2017 · For example: log 4 ≈ 0.477 log 4 ~ 0.477 Which statement is more correct? : Equivalence relation between elements and is proportional to

Jun 29, 2017 · My professors have seemed to use $≅$ and $≈$ pretty interchangeably to indicate that something is nearly equal to something else, and I just became aware of $≃$. When should we use …

Aug 16, 2017 · The reason is simply, that I reserve ∼ ∼ for the purpose of relations and proportionality. Both are mathematical concepts. If you have never used these two concepts, or if you don't need …

Jan 12, 2018 · What is the correct symbol for saying "equals, but is rounded"? For example: $$\\frac{1}{17}=0.0588$$ Is not essentially correct, since it's rounded. What other equal-like symbol …

Aug 2, 2017 · I have a question regarding the placement of the almost equal to sign in relation to the equal to sign. For example, can I write: $$129{.}87\\cdot 6\\approx 130 \\cdot 6 = 780 $$ or is it more …

Aug 6, 2019 · I have a measure X and the value of $X$ is equal to or almost $1000$. This can be $X=1000$, $X=999$, or $X=998$. Is it correct if I use the symbol $≃$ such that $X ...

Perhaps the correct option (and the one I am currently using) is $ (3)$ because of the transitivity of the symbols of equality $=$ and approximately $\approx$.

I am given a contour plot and one of the questions is to determine the sign of the second derivative with respect to x x at (3, 2) (3, 2): fxx(3, 2) f x x (3, 2).

Sep 26, 2020 · Any idea what they're asking for here? Are they just asking for coordinates? If so how would I find the coordinates? My eyes are telling me point C is at (1.55,1.55) but how am I supposed …
