Click For Summary

Discussion Overview

The discussion revolves around the methods for writing mathematical symbols in messaging applications like WhatsApp and Google. Participants explore various approaches, including the use of keyboards, apps, and coding options such as LaTeX.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • Some participants suggest that a keyboard may be necessary for typing mathematical symbols, while others mention the availability of apps that facilitate this.
  • One participant notes that on mobile devices, copying and pasting symbols might be the easiest solution unless a suitable keyboard is found.
  • It is mentioned that symbols like θ and ∫ can be searched directly in Google.
  • Another participant argues that for integrals, using words might be more effective than symbols.
  • There is a reference to the historical use of LaTeX for writing mathematical expressions, with an example provided.

Areas of Agreement / Disagreement

Participants express varying opinions on the best methods to input mathematical symbols, indicating that multiple competing views remain on the topic.

Contextual Notes

Some limitations include the dependence on device type (iOS vs. Android) and the availability of third-party keyboards, which may affect the ability to input symbols.

Do we need a keyboard for that.There are apps. Or can we write some code or latex? Or does whatsapp or google having so many developers even accept mathematical symbols like the θ sign or ∫ sign?

Are you on a mobile device? If so, you'll probably have to copy-paste them, unless you're on android and can find a downloadable keyboard with them.
The symbols you've placed in your post are directly searchable in google.
If you're looking for information regarding integrals, you're much better off just using the words.
Do any of those address your question? If not please clarify.

Ios supports 3rd party keyboards, too.
 
Once upon a time, people simply wrote latex, maybe without the backslash. int_0^x dx' sin(alpha x)=cos(alpha x) / alpha
