MHB TikZ Challenge 2 - Function Graph

AI Thread Summary
The TikZ Challenge 2 invites participants to create an impressive function graph using TikZ or the pgfplots package, with submissions due in two weeks. Each participant is allowed only one submission, which cannot be altered after posting, although descriptions can be edited. The thread encourages creativity and highlights the importance of showcasing unique features in the submitted graphics. Due to a lack of multiple entries, the voting process was deemed unnecessary. The challenge aims to foster engagement and skill development in creating mathematical visualizations.

Who can make the most impressive, interesting, or pretty TikZ picture?

This second challenge is to create a function graph.
We can use vanilla TikZ, or the pgfplots package, or... well... that's up to you!
If it's not immediately obvious, please mention what makes your picture special.

Please post your submission in this thread.
This thread will be closed after 2 weeks.
After that we will have 2 weeks to vote on what we think is the best TikZ contribution for this challenge.

Only 1 submission of a picture is allowed, and it is not allowed to change the picture after submission.
Any change to the picture itself will disqualify it.
(I'm leaving some wiggling room for editing the description.)
See http://mathhelpboards.com/tikz-pictures-63/tikz-announcement-22140.html for more information on how to create and post TikZ pictures.
To help create pictures we can use this http://35.164.211.156/tikz/tikzlive.html.

This picture uses:
  1. greg1313's method to add a title,
  2. lfdahl's method to add tick labels,
  3. MarkFL's method to add axis labels,
  4. Evgeny.Makarov's method to add neat arrow heads.
I like this picture because it represents the summum as I know it of function analysis (finding zeroes, extremes, singularities, asymptotes, and symmetries).

My credo, there's nothing wrong with stealing as long as we do it right (and learn from it)! (Bigsmile)​
 
Time is up.

Since there is only 1 submission, there's no point in voting.
Hopefully there will be more contributors next time.

Thread closed.
 
Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
