My professor draws sigma notation unironically like pic related, should I drop the class?

That's half a Schutzstaffel sign right there boy
Perhaps the professor is sigmafying the difference between convergence and divergence with the top and bottom lines of the sigma.
Actually I happen to know he had a stroke some time last semester, I think he used to draw them normally.
He is trying to tell you something.
You sound like the biggest dick in the universe now.
>indexing by k
>not by i
Drop that shit
It's a lot more common to need 2 indexes than 3, so it is more logical to use k and j (because they do not look alike), rather than i and j. It is still going in alphabetical order, just reversed.
Index by i, then k, then m, then j, then l, then n
You have to do it in alphabetic order to make it clear or it will be a hodgepodge of chaos.
>finite sum
>diverging
yeah okay
>indexing by i
>not by k
Good luck indexing complex expressions by i

I'm a jew and that's seriously unsettling because I'm the only who is taking that class
>not indexing by j
>not indexing by n
You people disgust me
>not indexing by x
...
>not using non-latin and non-greek symbols for indexing
literally a pleb

>that guy who draws his 1s like As
I never understood this meme
the fuck?
i,j,k are indexes, m,n are the upper, last term,. (is there a name for that part?)
Better than ones looking like a single stroke, good luck finding out if it's one or modulus sign, or if it's comma or one in subscript
>better than
It's not
this senpai, although sometimes j is used as te complex root of -1 to avoid confusion
I kek'd
Good luck indexing quaternions by k

>not indexing by pepe
Isn't that a hate symbol, user?
>showing up to lectures
what kind of pleb are you?

Strokes can have very strange effects on people.
Look up hemispatial neglect, for example.
>not indexing j instead of i
Only is you're a liberal faggot
