to do in the future: put a ton of people into a room (one at a time) with a radio with a joke and make the punchline a variable amount of time from the actual joke. Graph average laugh loudness vs time and find the optimal time for a punchline.
"that’s trivial and is left as an exercise for the reader"
The answer is trivial and is left as an exercise for the reader.

Can anyone explain why they do n+2 instead of n+1?
They are inserting (n+1) on n’s spot in the expression for u(n+1). In both the numerator and denominator n is multiplied with 2, which when inserting (n+1) is simplified to 2n+2
First, we write the system with the variables on one side:
Then, the augmented matrix (where A is the coefficient matrix and vector b is the right side in the system of equations) can be written and brought to reduced row echelon form like this:
and thus, the solution to the system of equations is
Mathigon presents the first fully interactive and adaptive mathematics textbook. Using beautiful graphics and animated simulations, it makes advanced mathematical ideas accessible to the general public.
Seriously cool website and a lot of fun to browse. Checkit.
Understandable introductions to advanced mathematics. The site is not only really interesting, but also gorgeous to look at.

You’re a mathemagician, Harry.
I’m going on a trip for the next couple of days, so I probably won’t be able to answer questions until the weekend
