\thickapproxThe \thickapprox symbol is used to denote that two quantities are approximately equal, with a thicker line to emphasize the approximation. It is often used in mathematical expressions where precision is not critical, and an approximate relationship is sufficient.
Indicates that 'a' is approximately equal to 'b' with emphasis.
a \thickapprox bShows that the function f(x) is approximately equal to g(x) over a certain range.
f(x) \thickapprox g(x)Represents the approximation of pi with the fraction 22/7.
\pi \thickapprox \frac{22}{7}
