- Difference between ≈, ≃, and ≅ - Mathematics Stack Exchange
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
- What is the approximate identity? - Mathematics Stack Exchange
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 described
- Is there a greater than about symbol? - Mathematics Stack Exchange
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 way to
- Approximate $\coth (x)$ around $x = 0$ - Mathematics Stack Exchange
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 $x = 0$
- real analysis - How to approximate $e^ {-x}$ when $x$ is large . . .
When the value of $x$ is small, such as when $x$ is less than $1$, we can use the Taylor series to approximate its behavior The first few terms of the series often
- How to approximate $\sin x$ without using trigonometry tables?
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" (
- When should we write $\approx$ (approximately symbol)?
