6:23 that's a good place to sneeze.
So apparently I could get into this university but I don't think I could have in 1989.
That is a standard Fredholm equation of the second kind. Anyway, nice solution.
Really enjoyed this problem, exactly at my level of problem-solving ability
An alternative method is to expand f as a power series around 0 (it's analytic) and then integrate the series from 0 to a by exchanging the integration and the summation, that will give the value of the constant (which is equal to f(0))
We literally learned max/min problems today! Very good overview in general of the topic, and a cool problem
No, I would not make it to the Japan University. But good video.
10:44
Very cool problem!
Kanazawa has one of the best gardens in all of Japan (kenrokuen) you should really go it's marvelous (also the Ninja Castle)
Going there in mid-March next year.
You call it DI method but I call it Bprp method :)
Been doing integration by parts for about 44 years and the first time I saw DI was on BPRP's channel. Very elegant!
2:51 how can you change the variables like that, can someone explain please ?
I want to know that too
Because the integral doesn't depend on the symbol you pick. You could draw a kitty instead of a t or an x and it would make no difference.

Nope.
Pleese donate me a powerful computer I have to find out new ec primes! Ec primes are the greatest discovery of this century!
