Math Whining Thread

*cue 30 minute quiz*
*skim over questions*
"Lol, I got this"
*There's only one at the beginning that seems like it will take over 50 seconds so I leave it until the end*
*24 minutes left*
"K back to that question"
*It's about bounds*
"Lmao this will take 10 seconds max"

"Given f and g are bounded, provide a rigorous proof for why f-g+fg is bounded as well"

23 minutes later

*used triangle ineq once*
*at the point where |f-g+fg|<=|f-g|+|fg|<=[blank]+MN*
*have been at this point for 23 minutes and 50 seconds*
*like 30 seconds left*
*writes "therefore y=|x|+sqrt(1-x^2) and y=|x|-sqrt(1-x^2)"*

*exit quiz*

And that is the story of how BOUNDS managed to screw me over on a test about FIELDS

Real question: holy sh1t what is the goddamn proof for the question

I hate getting proofs wrong because when I finally figure it out I see that the solution was usually right in front of my face the entire time. I'm fairly certain the proof takes like 2 seconds but I wasn't able to figure it out. Google says nothing, and everyone I've asked in the class either didn't answer it or they realized that they answered it wrong after a few minutes of discussion.

. . .

Yes.

frack me, I hated proofs so much.

Proofs is a lovely subject to study. It's just not a great subject to be tested on, because sometimes it doesn't even assess your abilities and instead assesses how well you can throw random sh1t on the paper and end up making sense out of it.

I don't even know what the OP is talking about...

Math is probably the most pointless subject I've ever learned about, closely behind chemistry

But without chemistry, you have no boolet for your nugget!

You mean to say it's pointless for your career, right?

Well I did say "I've", meaning it was pertaining to me. Somebody else may like it but it's not my cup of tea. If I were to ever become a narcs. investigator then it would be useful

What level math is this Goji?

Uhhh... first year uni?! I dunno what the system is like in the US. I'm certain it's different from the stuff I've seen in the UK.

closely behind chemistry

Chemistry was the bane of my existence last year.

feels super bad

You actually have to study college math, you can't just figure it out on your own anymore.

i'll start studying when i need to start studying. calc bc isn't difficult so far.

>tfw 83 on the math test

feels super bad

>tfw this test was out of 10
>tfw the question in the OP was worth 3 marks
>tfw I undoubtedly made some silly mistakes elsewhere

Realistic 5/10 right now.

First year uni? That doesn't even sound like anything I've ever seen on a math test and I've taken a shit load of math.

I really wished that I had the knowledge to help you...

Embrace it.

Maths is love. Maths is life.

*receives new problem set*
*does every question mentally*
"HAH maybe this time I'll make up for how I did last ti-"
"So everyone we will not be having a test on this unit and instead it will be due for homework"

I hate math. I was in pre-calc, then I had to go back a year because my shitty math course last year didn't teach me anything.

tfw getting top grades for maths at uni

git good scrubs

You do not know what suffering is regarding math until you take Calculus II. You literally dance when your test or quiz comes back at a score above 65. 

You do not know what suffering is regarding math until you take Calculus II. You literally dance when your test or quiz comes back at a score above 65.  Psst

Calculus, and all forms of it I've encountered [including Calc II] were really overhyped IMO. The questions are long and tedious sometimes, but in the end they're still not all that bad. Proofs on the other hand has me completely floored. And I both love it and hate it for that reason.

I do not want to take a math class in college...

You'll inevitably have to.  Any college you go to whether it be a tech college or a university will make you take an algebra course.

but it's easy as hell...

What topics are taught in the Calculus II course?

|f| <= M
|g| <= N
|f-g+fg| = |f+(-g)+fg|
which implies |f+(-g)+fg| <= |f|+|-g|+|fg| <= |f| + |g| + |fg| <= M + N + MN

Well I think I'll go bang my head on a desk a few hundred times now

I'm 1/cos(c) and you know it.
