Addition of Graph Embedding and Mathematical Functionalities to the Functions(Maths)

It will be great if we can add Graph Embedding and Mathematical Functionalities to the functions under the topic Maths and Trigo
https://www.arduino.cc/reference/en/language/functions/math/abs/.

Please find a modified example here: https://github.com/animeshsrivastava24/reference-en/blob/master/AsciiDoc_sample/Reference_Terms/Math_abs.adoc

Start by reviewing the Arduino math reference at the linked abs page and the proposed AsciiDoc example in Math_abs.adoc. Clarify which graph-embedding and mathematical functionalities are in scope, then identify the corresponding source pages; the work is done when the agreed additions are documented consistently in the Maths and Trigo reference.
