hard to appreciate the mockery when you legitimately believe "using trigonometry" means pressing buttons on your calculator.
You should find it suspicious you were never taught how to do sin/cos/tan angle calculation by pen-and-paper, unlike all the rest of the useful math you'd ever learned.

weird hill to die on, defending your own misunderstanding.

the problem seems worded incorrectly by the op's notion but is (apparently?) explained through the invocation of offsite linked problems.

the answer then isn't n!, but instead
[math]n! + \big(\sum_{x=1}^{n!-3}\enspace (n!-x)!\big) +(2)[/math]
where [math]+(2)[/math] is derived from the limit of the sum ending early to
[math](n!-3)[/math]
because the last addition is just
[math](n!-x)[/math]
rather than
[math](n!-x)![/math]
such that x at this point outside the sum is implicitly (x+1), solving the last sum as
[math]\big(n! - (n!-2)\big) = 2[/math]

it is a big number that wolfram doesn't want to solve. just the first 5 partial sums equal [math]10^{10^{11.96185045564416}}[/math]
with 87,178,291,192 more partial sums to go.

the n! solution is for individual binge viewings, every individual possible order of watching n-episodes in a unique order.
the sum solution is for a more mentally challenged problem, apparently the problem in question, of assuming the n! solution was itself a single continuous binge watch, and therefore if the entire problem and solution existed from simply beginning with episode 1 to produce a string of 87,178,291,200 episodes to have watched (beginning from the first viewing of episode 1), then there is another binge which instead started with any other episode, and more thereafter, such that it is seemingly decided that the end result is supposed to itself be a single binge watch with implicit "restarts" self contained.
the original non-haruhi problem seems to be about substrings of strings, mathematically as sets within sets.

the solution is too big for this to have any practical purpose. even if every episode could be viewed in a nanosecond, it would still take more time than has ever yet passed as prescribed by the Bazinga™ model of the universe.
desu the original non-haruhi "problem" was probably retarded too.
it's just a large number like Grahams.
