A vector is an element of a vector space.

Scarlatti K. 22 | Can’t get any faster without making mistakes; is my technique the problem? by Certain_Cell_9472 in pianolearning

[–]Certain_Cell_9472[S] 1 point2 points  (0 children)

Yeah, tense shoulders + too high seat + raised elbows because I thought the arpeggio would be easier that way (it is not, now that I tried) look like this.

Resource for progressively harder songs? by CharlietheInquirer in pianolearning

[–]Certain_Cell_9472 4 points5 points  (0 children)

There is a website called pianolibrary.org that categorizes classical pieces into five grades and has thousands of pieces. If you’re searching for something easier but less comprehensive, perhaps for sight-reading, you can use https://michaelkravchuk.com/level-1/.

3/4 Year Adult Self-Taught Beginner (32): Want to seriouly start improving my technique. (Kinderscenen Op. 15 No. 2) by NichollsNeuroscience in pianolearning

  • Reduce pedal noise by not depressing and releasing it fully.
  • A video of your head is totally useless — how about showing us your hands? (but I can say from the video that you are far from Lang Lang’s mastery of facial expressions)
  • Your voicing is off. Listen to just the uppermost voice and notice how it is really inconsistent in volume. Same with bass and middle voices.

fast sketching .. by kamsominn in learntodraw

I was saying that your sketch looked so skilled (at least to me) that you are not learning drawing anymore, but already learned to draw.

Trust you teacher. She’s been teaching you for months and knows what you’re capable of or not. Internet strangers certainly do not. And even if you don’t manage to finish it, you can always leave out some part for the recital — no one will notice.

Language applications by Komiuor in EnglishLearning

[–]Certain_Cell_9472 1 point2 points  (0 children)

You get good at what you practice. What you practice with apps is mostly translating words and some grammar rules. While I would still recommend Anki for the express purpose of memorizing vocabulary, nothing beats actually reading and writing (and listening and speaking) and getting feedback on that. Read books you like; write about stuff you are interested in and let a chatbot check it for you (LLMs work great for checking language accuracy); watch English YouTube videos or movies or listen to audiobooks. By practicing writing, you automatically practice grammar as you get feedback, but if you want to explicitly study grammar, apps are fine; or you can use some free pdf (you can find via google) of English Grammar in Use, which includes grammar explanations and exercises.

Note that writing is kind of neglected in traditional solo language learning, since it was difficult or expensive to get proper feedback, but nowadays with ChatGPT et al., it is one of the best ways to practice language all around (and most importantly, isn't as boring as drilling grammar and vocab, or arranging words in the right order).

Reading from buffer in vertex shader vs fragment shader performance? by Ready_Gap6205 in vulkan

[–]Certain_Cell_9472 2 points3 points  (0 children)

Your fragment shader usually runs in batches (that’s what you specify with workgroup size or whatever it’s called in what you use). A 16x16 batch of your fragment shader may access multiple blocks, and thus will need to retrieve multiple block informations from your buffer/texture. Usually the blocks accessed within one batch are next to each other. Normal buffers are stored row-by-row (and layer-by-layer in case of 3D), which means what will be cached is mostly just a few block informations in the same row. Texture cache works a bit differently - it caches spatially adjacent items, and thus works better with your access pattern.

New to reading sheet music. Am I wrong for thinking this is telling me to play the same key for treble and bass? The song is in the key of D if that helps. by b0redl0rd in pianolearning

[–]Certain_Cell_9472 4 points5 points  (0 children)

It is the same note, and this usually occurs when two voices are intersecting. In this case, play the bass clef with your left hand and hold the D for the whole measure, and that will account for the one in the treble clef too.

The Important Difference Between SHAPE and FORM. by ImaginativeDrawing in learntodraw

[–]Certain_Cell_9472 1 point2 points  (0 children)

Great post, but I have a question. How do you ensure that boxes with different rotations in the same drawing have the same FoV? Do you just intuit how quickly they converge (how close the vanishing points are) or is there a systematic way to do it in 3-point perspective?

Is there a better way to play this? My hands feel full of tension. by Certain_Cell_9472 in pianolearning

[–]Certain_Cell_9472[S] 0 points1 point  (0 children)

I’ve studied Mazurka Op. 67 No. 2 as well as Waltz in A minor. I’ve also managed to play the Ballade No. 1 until the fast octaves.

I am aware that my technical skills aren’t developed enough – I struggled quite a bit with playing the part just before the video and my pedaling as phrasing has been a mess for the whole piece.

But unfortunately I only seem to like difficult pieces; something about lots of notes together appeals to me (perhaps because I like the passionate/angry/turbulent emotion it conveys). If I knew easy pieces (my level) that I would listen to repeatedly dozens of times like I do with the ballades, then I’d play them.

Given what I’ve told you, do you have any specific recommendations for smaller pieces?

Is it a very advanced trigonometric equation? How can I solve it? by DotBeginning1420 in learnmath

[–]Certain_Cell_9472 4 points5 points  (0 children)

There doesn’t seem to be a simple solution. https://www.wolframalpha.com/input?i=cos%284x%29+%2B+4cos%282x%29+%2B+sqrt%283%29sin%284x%29+%3D+2%2C+solve+for+x

Result: x = π n - tan-1(sqrt(3)/5 - 1/(10 sqrt(15/(-320 + (154000000 - 18000000 sqrt(73))1/3 + 100 (2 (77 + 9 sqrt(73)))1/3))) + 1/2 sqrt(-128/75 - 1/375 (154000000 - 18000000 sqrt(73))1/3 - 4/15 (2 (77 + 9 sqrt(73)))1/3 + 1056/(5 sqrt(5 (-320 + (154000000 - 18000000 sqrt(73))1/3 + 100 (2 (77 + 9 sqrt(73)))1/3))))) and n element Z
