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...

One can, for example, approximate continuous functions with polynomial functions, in which case the idea is to keep the area between the original function and the approximating function small. One can …

Feb 25, 2017 · An approximate identity (in the sense that you've described) is a sequence of operators, usually derived from some "nice" class, that converge to the identity operator in the sense that you …

Jul 7, 2017 · And he could approximate small values by performing some mental math to get an accurate approximation to three decimal places. For example, approximating $e^ {3.3}$, we …

Jan 1, 2023 · How to approximate $e^ {-x}$ when $x$ is large Ask Question Asked 2 years, 11 months ago Modified 2 years, 11 months ago

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

Apr 12, 2016 · I have been wondering for a long time whether there is a unequivocal way to define and use the symbols commonly adopted for an approximate equality between two quantities. I am a …

Apr 13, 2017 · I'm trying to approximate $\coth (x)$ around $x = 0$, up to say, third order in $x$. Now obviously a simple taylor expansion doesn't work, as it diverges around $x = 0$.

Basically, to approximate the location of a root of a function, we approximate the function locally by its tangent, find the tangents root instead, and that value is a decent approximation for the location of …
