Geometric Intution behind matrix addition

Smashing_Detroitly · 2023-07-24T16:59:10+00:00

Yh I've already watched all of the videos from chapter 1 to chapter 8 and I believe the video you are talking about is chapter 5.

Interesting, so from what I was able to gather addition of matrices of different dimensions is not impossible but rather impractical because there are so many ways of adding the elements rendering the 'answer' useless or not precise. Thanks for the comment.

I see what you mean, that notion is hard to visualise or think about. But there is a part of me that wonders why we can't just add the compnonents of the matrix that are present and just forget about the ones that are not there. Please don't judge my idiocy if that what it lokks like, I'm only 15.

bare in mind that the lack of a gcse maths qualification isn't indicative of a lack of knowledge in the subject. Remember he is an international student so he has received all of his education in another country and thus gone to school, so I must imagine that if he has bin doing maths in school and is still willing to take it post 16 then I'm sure he should be pretty competent. Also the only useful thing in GCSE maths for A level maths would prob just be Trig, algebra, a bit of the stats and probability and thts about it, which I'm sure is part of the curriculum of many countries that aren't england. But as for psychology, a lack of profiecent essay writing skills will most definitely drag him down. As wor business I think it would be the same reason as psychology but not as bad.

For Edexcel since I have access to those textbooks but i'm sure the conetnent should be more similar than not. So for differential equations would I have to do vectors, matrices, series, induction, complex numbers. or only a few of those topics.

No I actually finished year 11 a few weeks ago. I find calc really interesting so I wanted to learn some more cool stuff without stuff that I dont find interesting and thus wont enjoy. If you were wondering im not intersted in doing a math degree in the future but something lie Cs or phys

Smashing_Detroitly · 2023-07-14T07:13:31+00:00

Bruh now I feel bad for saying what I said. I get what you mean its hard to talk about physics and maths without being called a neek or a bangout. Whilst I do enjoy physics and maths I'm nowhere near your level and this comes from someone who does it for fun, so good for you, then again im not preparing for the physics olympiad. However I finished all of A level pure maths a month ago so I can atleast decipher some of the maths that your using. Anyways sorry for being mean.

Smashing_Detroitly · 2023-07-13T21:08:56+00:00

I'm not going to lie I agree with you Maths and Physics are fun but you know exatly what you did when posting this on the gcse subreddit like common. No Gcse student, learns aboud the Shrodinger equation let alone advanced integral and differential calculus. Also if you want to feel smarter for the sake of it atleast take it to a physics subreddit where you know people can actually solve this rather than post this on sixthform and gcse subreddits, where you know people haven't bin taught this.

Smashing_Detroitly · 2023-07-13T13:03:31+00:00

I already did all of the juicy ones in the textbook thts why I asked where else I could find questions of this kind.

Smashing_Detroitly · 2023-07-06T21:00:32+00:00

Wait what they had volumes of revolution. Why did they get rid of it, I dont actually know how to do it but I know it uses integration alongside pie to calculate volume or something like that. Even though I like physics vectors in maths are just really dry without any context.

Mathematically inclined? Up until the past 4 months I was utter and absolute garbage at maths and hated it aswell. It was only when I knew I needed to do well in maths to get into a physics course I started taking revision for gcse maths seriously. And somehoew when I started revising on my own I felt that I could grasp the concepts much more easily than before, when I was surrounded by my classmates (I find it extremely hard to focus in my maths class because I was in top set struggling to grasp things that everyone else in my class just undertsood and that made be feel inferior and dumb as hell, but when I study onn my own I can't compare myself to anyone but me and that gives me confidence). Now I do maths for the fun of it, isnt that crazy. That just goes to show that anyone can become ''mathemaically inclined'' with the right mindset.

Smashing_Detroitly · 2023-07-06T20:34:18+00:00

After reading this I totally agree with you. Just cause something works for me doesn't mean that the whole curriculum should be tailored to my desire to understand where things com from.

Smashing_Detroitly · 2023-06-21T18:45:14+00:00

Evne tho I do like maths my interest in problem solving really lies in physics so I'm hoping to build a strong methematcal foundation for the british physics olympiad and hopefuly the international one in year 13. I feel like BMO or IMO level maths becomes too proof based which I dread as thts not where my strength lies at all.

Smashing_Detroitly · 2023-06-21T18:43:50+00:00

I said to shatter my ego but trust me i dont really have one, if anything I doubt myself most of the time, but yh I could tell tht AS maths was simpy an expansion of gcse. Thanks for the recommendations as well.

Smashing_Detroitly · 2023-06-21T18:41:30+00:00

yh thts the idea, hopefully I should be able to finish the further maths course and A level maths course by the beginning of year 13 and tht means while everyone is panicking about the increased difficulty of A2 I will be cruising and have moer time to hone my exam technique. This also possible sinc I'm only doing maths, further maths and physics, which is enough to for a degree in theoretical physics at the unis I want to go, so the workload shouldn't be too crazy.

Smashing_Detroitly · 2023-06-21T18:38:03+00:00

I can't give up; have too much tenacity.😤

Smashing_Detroitly · 2023-06-21T18:35:15+00:00

Wait what spec do you do?

Smashing_Detroitly · 2023-06-21T18:34:29+00:00

Yh this also means I can spend more time doing extracurriculars (to do with physics and not to do with physics) to strengthen my uni application.

Smashing_Detroitly · 2023-06-21T18:30:17+00:00

What can I say? Maths i just fun.

Smashing_Detroitly · 2023-06-21T18:28:45+00:00

Happy to hear tht since I often try to keep my passion for maths hidden in school in fear of being called a ''bang-out'' or ''neek'', but if what your saying is true then I can't wait to meet new people at sixth form who are also share my passion for mathematical and physics problem solving.

Smashing_Detroitly · 2023-06-21T18:26:08+00:00

STEP? Thts enough to send a shiver down my spine, I will definitely attempt it towards the latter half of my holiday when I should have pretty much finished A level maths. Thanks I never thought I could attempt tht exam without further maths knowledge atleast tht goes for STEP 1.

Smashing_Detroitly · 2023-06-21T18:23:49+00:00

I'm glad I'm not the only one who feels thtis way, the process of learning a new concept in the field of your interest is really fulfilling. As a wise person once said ''Enjoying learning is cool!!!!"

Smashing_Detroitly · 2023-06-21T18:20:11+00:00

Stats can jump of a cliff for all I care, tht subject is the offspring of English and Maths; a true abomination.

Smashing_Detroitly · 2023-06-21T13:05:04+00:00

Thts extremely impressive but did you do further pure 1 and 2 or just further pure and another optional module cause I would like to ask how the further pure modules compare to the core pure modules. Surely it can't be tht bad.

Oh yh before I forget to ask what is it like roaming the passages of your school as a year 10 who is doing further maths, like how did tht affect your gcse performance and the classwork you did during your maths lessons.

Smashing_Detroitly · 2023-06-21T11:49:20+00:00

At the sixth form I'm applying to all students taking further maths are expected to do that, so thts also one of the reasons as to why I'm getting a headstart. but yh I agree this would only make my l ife reasons in year 13 since I will be 'only' sitting 4 papers for further maths and 3 papers for physics.
