wtf is a dot product

Damn I just got rejected from medschool again. This is the third time I reached the final stage and got rejected because I failed at the interview stage. I just needed to be average cause my academic scores was already above the median. I must be a full blown autist for me to flop so hard at the interviews.
Now I have to deal with not getting to med yet again. It just hurts when I'm such a fucking brainlet. Seriously considering just giving up cause if I'm struggling to get in now, it probably doesn't bode well for a potential career as a doctor.

Tfw electrical and electronics engineering masters degree, but just too burnt out too work in the field.

A function is a relation.
Let:

[math]f_{1}\subset \{0\}\times\{0\}=\{(0,0)\}[/math] or [math]f_{1}:\{0\}\rightarrow \{0\}[/math].
[math]f_{2}\subset \{0\}\times\{0,1\}=\{(0,0),(0,1)\}[/math] or [math]f_{2}:\{0\}\rightarrow \{0,1\}[/math].
[math]f_{1}(0)=0[/math] so [math]f_{1}=\{(0,0)\}[/math].
[math]f_{2}(0)=0[/math] so [math]f_{2}=\{(0,0)\}[/math].

So the the functions are equal despite being "defined" on different sets.
Can anyone clarify this?

Finish any book in ~1 week (cross-referencing, exercises and rearranging take longer).
Access every page I've ever read in my mind's eye.
Get from my spirit guide more information than I'll ever be capable of elaborating.
Drug myself to sleep because I can't handle it.

Can I ask you guys something?

Taking high doses of Vitamin C used to work extremely well for my constipation 3 years ago but it stopped working and now does NOTHING.

Why would this happen? Why?

Lack of proper cofactors? But isn't it just vitamin C that causes your bowels to go? It doesn't get changed into anything else right?

Is my stomach acid(or my inflamed duodenum) breaking down the vitamin C?

Is it not getting absorbed?

I know your body dumps excess vitamin C into your intestines(which causes you to go) but why isn't mine doing that?

If I took vitamin C enemas, wouldn't it go to my liver and my liver would dump it into my small intestines?

PLEASE HELP because the countless doctors I've been to have done absolutely nothing for me and I've resorted to figuring this out on my own and paying for 3rd party tests. I'm so bloated right now and have chronic fatigue, countless food allergies, anxiety, ocd, panic attacks, itchy as fuck.

I hate the fact that I'm so dumb.
