thickapprox
Denotes a stronger or more emphasized approximation relationship between mathematical expressions.
Overview
Provides a visually distinct, thicker version of the standard approximation symbol, useful when emphasizing approximate equality or when multiple levels of approximation need to be distinguished in mathematical writing.
- Common in numerical analysis when highlighting primary or important approximations
- Used in mathematical proofs and theoretical computer science to show stronger forms of approximation
- Particularly useful in documents where regular and emphasized approximations need to be visually distinct
- Often appears in optimization theory and computational mathematics
Examples
Expressing a rough numerical approximation with emphasis.
\pi \thickapprox 3.14159
Indicating approximate equality between two expressions in statistical analysis.
\hat{\mu} \thickapprox \frac{1}{n}\sum_{i=1}^n x_i
Showing approximate equivalence in numerical methods.
f(x + h) \thickapprox f(x) + f'(x)h
