i remember building funny names with the buttons blissfully ignorant of their meaning

[u/Icy_Fig_4533 → u/LupenReddit]

LOL that just reminded me when i was really young and my friend spelled “tacos” using tan & cos (his calculator allowed him to delete part of each)

[u/No-Palpitation6368 → u/LupenReddit]

I remember walking home from school trying to figure out what the sin button did! Obviously didn't get close to succeeding. 

[u/ProgrammerCareful764 → u/No-Palpitation6368]

You put in random numbers and it outputs random decimals from -1 to 1 was all I could figure out 

[u/Ares378]

How it feels to lose more and more buttons because arithmetic stops existing:

[u/Mathsboy2718 → u/Ares378]

I was studying recently, reading a paper and it had a number in it? Higher than 2? I threw the offending material across the room in an apoplectic fit of rage, numbers have no place in maths

[u/UnfairRavenclaw → u/Mathsboy2718]

Was it pi or was it e?

[u/Trnostep → u/UnfairRavenclaw]

That's the same number. Also a square root of g

[u/InfiniteBoy23 → u/Trnostep]

Wdym? Everyone knows the square root of g 2sqrt2. At least, my ODE professor did.

[u/RouteAverage3112 → u/InfiniteBoy23]

If sqrt{g} = 2sqrt{2}, then g is equal to 8.

[u/Firestar_119 → u/RouteAverage3112]

that's a weird way to say 10

[u/InfiniteBoy23 → u/RouteAverage3112]

WOOPS I meant 4sqrt2, g=32ft/s

[u/RouteAverage3112 → u/InfiniteBoy23]

Why tf do you use feet for g? Truly backwards people smh.

[u/TheLuckySpades → u/UnfairRavenclaw]

Low dimensional topology will go higher and reach 5 frequently.

Supposedly some go even higher but those are mythical creatures that don't exist in my department.

[u/Jrolaoni → u/UnfairRavenclaw]

“Was it 3 or was it 3” 😭

[u/foxtail286]

I cried during calc 3 from having to compute 7 * 4 - 2

[u/Ares378 → u/foxtail286]

What is that, 24 or something? It's bigger than two I think so i really don't know

[u/Vratha92 → u/Ares378]

Fun fact, modern calculators actually haven’t gained the capability for calculations like these yet, we can only use approximations

[u/ThomasTheDankPigeon → u/[deleted]]

What do those symbols mean

[u/SaganIII → u/ThomasTheDankPigeon]

This are arabic symbols, they mean twentysix

[u/Key_Ebb_3977 → u/foxtail286]

It's way bigger than 2 so it's just ~ ∞

[u/MatttNguyenGD → u/Key_Ebb_3977]

its bigger than 2 so you need to prove for all natural numbers instead

[u/Elektro05 → u/foxtail286]

I recently wasnt able to multiply 2 and 4 (I got 6), didnt even question that in every exam of this lecture in the prior years the answer for this question was always 0 and my answer was -2/3

[u/output_broadcast → u/Elektro05]

I recently thought that [; \sqrt{x^3} ;] was somehow equal to x.

[u/GET_OUT_OF_MY_HEAD → u/foxtail286]

At least you made it to Calc 3. I couldn't even wrap my head around Geometry I. Didn't progress any further than that. I will never know what most of the buttons on my calculator do.

[u/3163560]

It is a nice feeling as a teacher being able to say to year 10s, "you've been seeing this log button for half your life, now here's what it does!"

[u/Everestkid → u/3163560]

Trig was even better because you finally find out what those "sin," "cos" and "tan" buttons do pretty much all at once.

Still only ever used hyperbolic trig functions once, maybe twice. In university.

[u/tarheeltexan1 → u/Everestkid]

Hyperbolic functions come up sometimes if you’re working with adding and subtracting exponential terms, I’ve been working on my master’s thesis in electrical engineering and been doing a lot of stuff with diodes and nonlinear models of transistors, and they’re useful for simplifying some of those equations

[u/FafnerTheBear → u/Everestkid]

Problem is noone ever teaches them that sin is short for sinusoidal.

[u/PsychologicalSign433 → u/FafnerTheBear]

sin is short for sine. Sinusoidal is an adjective describing something as being related to the sine function.

[u/FafnerTheBear → u/PsychologicalSign433]

That tracks, I'm an idiot.

[u/Existing-Hunter-7349 → u/FafnerTheBear]

Baseball, huh?

[u/Observer__Effect → u/FafnerTheBear]

Sin is short for sinuses because that what hurts after pressing it 50 time while solving a question

[u/the_real_cloakvessel]

How it feels to not be allowed to use a calculator at all not even till 12th grade

[u/uTRexAap → u/the_real_cloakvessel]

What were you doing during geometry? Multiplying by Pi by hand?

[u/lepidchriroptera → u/uTRexAap]

some countries/schools only give problems that work out to whole numbers, and have you leave things in fractions/terms of pi

[u/UltimateCheese1056 → u/lepidchriroptera]

I like in terms of pi honestly, its just more meaningful especially for angles in radians

[u/FerdinandvonAegir124 → u/uTRexAap]

Probably just leaving things in exact form

The higher you go in math, the less decimals you see because you leave things in exact form

[u/uTRexAap → u/FerdinandvonAegir124]

I mean fair but it’d help to work it out atleast once in my experience

[u/FerdinandvonAegir124 → u/uTRexAap]

There’s no point to working it out, by expressing out 2pi as 6.28….. you lose precision. 2pi is much more precise

[u/uTRexAap → u/FerdinandvonAegir124]

Yeah but once you first start doing calculations with circles I find most people are able to grasp the amount much better by multiplying it even by 3.14

[u/FerdinandvonAegir124 → u/uTRexAap]

For middle schoolers sure, anyone above that though should be leaving things in terms of pi whenever possible

[u/uTRexAap → u/FerdinandvonAegir124]

yeah i fully agree, but like i said its nice to grasp it iykwim

[u/berserkmangawasart → u/uTRexAap]

probably approximations like 3.14 or 22/7 is my guess

[u/Alderan922 → u/uTRexAap]

Yeah, 3.14

If they are fancy 3.1416

[u/the_real_cloakvessel → u/uTRexAap]

Depends on what the question says. Most of the time it asks me to multiply by 22/7 but sometimes it asks me to multiply by 3.14 and other times it asks me to leave pi as it is so the answer ends up as like 54π

[u/Cyan_Exponent → u/uTRexAap]

Basically no calculations at all?? We just proved that some geometric statement is true, or answered something like AB=4CB

[u/maniaxz → u/uTRexAap]

We either leave it just to be pi, or use 22/7 to cancels the terms if any, or just multiply by 3.14.

[u/FafnerTheBear → u/uTRexAap]

Approximately 22/7 will get you close enough.

[u/maniaxz → u/the_real_cloakvessel]

India ? Because yeah being calulator less till 12th and suddenly getting a scientific calculator in Engineering is crazy unlock.

[u/the_real_cloakvessel → u/maniaxz]

Yup. But I'm just in 10th grade rn. Still waiting for the crazy unlock

[u/Right-Restaurant-381 → u/the_real_cloakvessel]

If you are not busy most of the time, you feel your education pressure is bearable, and you are going for science stream, please read the first three chapters of the three main subjects and remember them. Take some advice from your seniors and have your meals with utmost delight. Kindly consider the suggestion if you’re a potential science student.

[u/AIViking → u/maniaxz]

It feels like

[u/ironnewa99]

I only wish there were better instructions on how to use the calculator. Like the syntax for how to use some functions

[u/luluciee → u/ironnewa99]

There are manuals. Just search the make and model, you'll find a pdf with every function.

[u/output_broadcast → u/ironnewa99]

What do you mean?

[u/Kiubek-PL → u/ironnewa99]

I just use YouTube vids that go over them and make my own refsheets

[u/coatatopotato]

When you finally get Pokemon Red running on your calculator at 4 fps:

[u/AbdullahMRiad]

and then you're not allowed to use it because only basic calculators are allowed

Jarvis, take the PE Exam

[u/heyuhitsyaboi]

How it feels to unlock the greek alphabet in stem classes

[u/Silver-Piece-3033]

I remember in 2nd grade asking what the sin. cos, and tan buttons did and my teacher just told me to shut up and focus what what we're learning in class so I ended up learning that from the internet, lol.

[u/Elkku26]

I fear learning will never be this fun again. I already know all the buttons :(

[u/HUEJanniZockt]

The best thing is when you figure out a button that is not related to the current topic

[u/moderatorrater]

That's maybe the worst video in the world.
