# Approximation icon : Is $\pi \approx 3.14\dots$ equal to $\pi \fallingdotseq 3.14\dots$?

This could be an unimportant inquiry, yet what is specifically the distinction of in between these 2 expressions? Am I deal with to mention the both mutually whenever I require to share the approximation of $\pi$? I'm little bit overwhelmed as here, it mentions $\pi$ can be share by $\fallingdotseq$ as it's not a sensible number, yet $\pi$ can additionally be shared by a collection (asymptotic ), so it needs to be $\approx$ too.

$$\pi \approx 3.14\dots$$ $$\pi \fallingdotseq 3.14\dots$$

Any mathematical symbols is ok as lengthy as it prevails expertise in your area. As an example, I think I totally recognize the definition of the $\approx$ icon. Nonetheless, I have not ever before seen the 2nd icon you gave.

To be on the certain side you need to give a definition of any kind of relationship icon you do not take into consideration to be open secret. This might take place as a brief statement (" ..., where $\approx$ represents ...") or possibly as a table of the made use of icons in the front issue of your job. Similar to any kind of definition in maths, there is no right or incorrect in the symbol/notion/etc you make use of, just correct or unbalanced interpretations.

Additionally : When doubtful, make use of the icon that is made use of even more generally in the typical books of your area. There is no advantage in being avant - garde at symbols.

While it is absolutely real that with the correct definition there is currently 'incorrect' symbols, probably it needs to be stated that some symbols is extra symptomatic and/or less complicated to collaborate with than others, as an example Arabic character vs. Roman characters, the numerous icons for the by-product, and also plenty of others. The real icons are approximate, yet excellent symbols can absolutely advertise the circulation of suggestions extra conveniently.

Additionally, do I bear in mind appropriately that Feynman surrendered attempting to design extra reliable symbols for straightforward mathematics when he was fairly young due to the fact that no one could recognize what he was doing?

An excellent symbols has a nuance and also suggestiveness which sometimes make it virtually feel like a real-time educator. - - Bertrand Russell
