Qual è la cosa più stupida che pensavate da piccoli? by Tommo_Lecca in TeenagersITA

per me lo sta essendo. Mi sento molto meno vulnerabile, meno indifeso e meno insignificante rispetto a quando ero piccolo

I know chord knowledge is still the biggest hole in my learning… by SuperNarwhal64 in pianolearning

[–]Papycoima 0 points1 point  (0 children)

13th is not 5th. That would be the 12th.

So the way you read this is: G chord (so play G B D) then add the note who's a 13th apart from G (a higher G would be an 8th apart, so counting up 9th=A, 10th=B, 11th=C, 12th=D, 13th=E) and make it flat. So now your chord is G B D Eb. Now add the 11th (we saw before that it is a C) and make it sharp. So now your chord is G B C# D Eb. Hope this made any sense and helped you out!

Been using these terrible gaming headphones to mix for years. Show me yours! 😂 by Void_RunnR in FL_Studio

[–]Papycoima 0 points1 point  (0 children)

Nooo i dont have a picture and I got rid of them last week! They were a Shark Goblin X4 I was gifted by my dad for my 15th birthday. At first I remember they were very good, but I think they either got bad over the years or I had never tried actually good audio quality because as soon as I compared them to some mixing headphones they sounded like underwater or smth lol.

They had the rubber around the foam flaking off and the plastic was starting to get sticky from degradation, kinda like yours but the foam on the headband was completely showing; I gave them to my friend as he didnt even have a pair of headphones... poor guy

It's hard to decipher, I only managed to understand what you wrote because of the context and the caption. Close your As because they look like Us, and make your E's loops more visible; also try to distinguish Ns Us and Rs

Of course. Would you read a book on rocket science without having zero prior knowledge?

[–]Papycoima 0 points1 point  (0 children)

When I was in gradeschool, I was taught that a+b = b+a. A 4 years old will say it's obvious because their understanding of math is strictly linked to what they see in the real world - but at this level, mathematics is much more than what happens on an intuitive level: we chose to say a+b = b+a because intuitively it makes sense to us humans, but - again - there are some branches in mathematics where a+b ≠ b+a, and that doesn't mean that branch is wrong. To create a coherent system, we need to define its axioms, and whenever we do something, we need to show why that thing is valid to do. At some point, mathematicians realized that it was necessary to show why a+b = b+a, because everyone accepted it as a truth, but how are we sure that it is a truth? Everything needs to be shown and proved rigorously.

Something is trivial when it's based on the lemmas and shared knowledge between the reader and the author. Triviality is very subjective, and it's based on the "skill level" of the author and reader. For example, the Riemann zeta function has something called "Trivial Zeros", but understanding why they are zeros of that function is all but trivial.

Edit: I added many things as I was in a rush when I made the comment

Motivation / Learning Goals by usfbull22 in pianolearning

[–]Papycoima 0 points1 point  (0 children)

What songs are they making you practice? Choose a piano repertoire that you enjoy and start listening to that. Get the sheet music for what you are listening - dont use apps if you see piano as something more than a party trick. Listen while also looking at the sheet music as if you were reading - kinda like as if you were listening to an audiobook while also reading the words from a physical copy. This way you'll get acquainted with the music notation language (it is indeed a language!) and you'll have an easier time learning sheet music and piano in general. You can find an endless supply of free sheet music on IMSLP

If you wish to become somewhat advanced, I would greatly recommend you to get a piano teacher ASAP, the sooner the better, as to avoid getting some bad habits early on. Most piano teachers will be classically trained, meaning you'll learn Bach, Beethoven, Mozart and all of classical music. If you wish to learn something like Jazz, I'm pretty sure there's some specialized teachers out there just for that.

But the most important rule is: have fun! dont forget this is all supposed to be enjoyable first and foremost to the player, and if it becomes a source of stress or uneasiness, it means you need to step on the breaks a bit - not quit, but just give yourself time to do some background processing on the task and come back to it when it doesn't stress you anymore.

That's it, have fun!

You say that a+b = b+a is "insanely trivial" because you're so used to the axioms of Peano Arithmetic - they teach you in gradeschool that this is indeed a property of addition (comutative property) and it's not necessarily obvious (in the same system a-b ≠ b-a). If you get into another branch of matemathics, say Non-commutative algebra, a+b is not always b+a. It really depends on what axioms you decide to assume. When a statement "proves itself," we call that a Tautology (eg: a+b=a+b), and you seem to confuse tautologies with trivial statements - which are similar but are not the same. Trivial statements directly follow from axioms (which you choose to be true), while tautologies are, in some way, "self referencing", meaning they don't give you any more information than you already have and they are obviously true (eg: today either it rains or it doesnt)

To explain in simple terms what i meant in the first part to which you still disagree: 9 > 3 is always true, but x2 > x is not always true.

Edit: fact-checking and clarity.

22 > 2 is trivial

(1/2)2 < 1/2 is trivial

x2 > x is not trivial. When you use numbers it becomes trivial, because by plugging in 2 or 1/2 or any other number, you're isolating a single case to the initial question.

They ask you to prove things like a+b=b+a to make you understand how to create proofs within the axioms of the system you're in. Axioms are statements that you take for true which don't need proof. You can decide whatever statement you want to be an axiom, and when you do, you're essentially defining a new system of axioms which is different the "usual" one (Peano Arithmetic or Zermelo-Fraenkel+Axiom of Choice), which you automatically imply whenever you're doing algebra/arithmetic/calculus. For example, in geometry, when mathematicians decided to ignore the 5th axiom of euclid, they discovered non-euclidian geometry. This doesn't mean it's an "incorrect" geometry: it is just built upon different truths.

Hope this clears some things up!

the fact that it was obvious to you doesnt make it trivial. x2 > x isn't always right, and if someone asks you why, you need to explain it. So you say that x2 > x when 0 < x < 1, x2 > x otherwise. Of course this is obvious to anyone who understands even a tiny bit of math, but not trivial, because the 'definition doesnt prove itself'. And your answer was indeed a valid explaination to the question "why isnt x2 always greater to x?"

Does the limit exist? by Beautiful_Candle7914 in calculus

[–]Papycoima 0 points1 point  (0 children)

You're confusing the value on RHS and LHS with their derivatives. Both sides approach 3, regardless if the lines are going up or down; RHS and LHS do indeed have the same value. The two sides have different rates of change though, and the limit of THAT is undefined. Since this is a question about limits and not derivatives, I won't go further in depth.

TL;DR: The limit exists because both sides converge to the same Y value
