Hello!

To make up for the lack of an "upper division" in the subreddit math competition this year, I took it upon myself to organize a separate exam that is significantly more discovery and proof-based than any exam held in the community previously, and to host it on the 2nd year anniversary of the Discord server being made available to the public.

The next exam of this kind will be held in Mid-June 2027.

The exam (which includes its rules) is linked at the bottom of the post. The top 5 winners will be announced, and the top 3 winners will receive the following (or something of equivalent value upon negotiation):

1st Place - A Math Textbook of the Winner's Choice (~$45 USD Value Limit)

2nd Place - Basic Discord Nitro, 1 Year Subscription ($30 USD Value)

3rd Place - Fulltouch Hagoramo Chalk 72 pc ($25 USD Value)

Special thanks to u/dopplerspectroscopy and zzz on Discord for their tremendous help in writing the exam and agreeing to help grade some submissions; couldn't have done this without their help.

Edit for story:

Basically, I was asked to find out when we needed to switch parts based on seasonal temperature fluctuations. So I took the data and did least squared regression using a sinusoidal function. Then to took the second derivative of the resulting function to find the seasonal inflection point (haven’t use thay word in a while) which indicates where the season is most rapidly changing between hot and cold.

It’s no triple integral over spherical coordinates in epstein space, but it required python!

Context 2: I am an Engineering Data Analyst, but have mostly been doing software development, not actual analysis.

Notations Yk wots deep? Integrate Y wrt k (Y being a constant) and it goes from Ydk to Yk(+c) . Hence it shows life goes from ignorance to knowledge.

Multiplying or dividing temperature must be done with absolute scales.

Ever since I found this out, the story of the Furnaces of Nebuchadnezzar in the Book of Daniel became more amusing because the king technically would have to order them be heated to a much higher temperature than most people would expect he did.
