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 …

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 …

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 $x = 0$.

An Opening Note : First of all, I want to make this very clear that by the phrase "without using trigonometry tables", I mean without using them to find $\\sin$ values of the "non-standard angles" (...

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 …

Aug 12, 2015 · To indicate approximate equality, one can use ≃, ≅, ~, ♎, or ≒. I need to indicate an approximate inequality. Specifically, I know A is greater than a quantity of approximately B. Is there a …
