I'm in early highschool(don't wanna say age srry)

I'd like to explore more maths, see different methods and see how it all relates. But i'm finding this hard to do on my own when YT videos don't usually provide this as they're just helping ppl for the exam and not bothering with the fun bits.

Any clubs/communities/forums online where people talk about different approaches or methods of solving questions?

I know i'm in one rn but I was thinking smaller ones with people who are at around the same level as me. (algebra 1 and 2, geometry, precalc or GCSE/iGCSE)

Preferably people with a more advanced understanding of maths helping ppl at my age or level! (bc i'd assume their deeper knowledge could provide different perspectives and approaches)

I don't want to learn maths for exams I want to learn it for fun basically

Maybe on like a discord or a google classroom? If there is a Reddit community for this pls direct, and if anyone has invites to servers or smthn🙏

I shouldve probably classed this as a question but nvm

How would you go about solving this?

So I've scaled down a vehicle down by 1/10th and the speed of the original model was 320km/h.

I believe the scaled down speed was somewhere around 80km/h but I'm not sure how it is calculated. Does anyone know?

I'm trying to do a CFD Simulation of a 1999 Mercedes CLR-LM

I'm not sure how to solve this it's for algebraic expressions. Help would be greatly appreciated

in triangle OAB, OA and OB are denoted by a and b respectively. Show that OG=1/3(a+b), here G is centroid of triangle OAB

dumbest question ig but I'm a physics, chemistry major and I've lost touch with mathematics as I did not study it throughout my undergrad. what is the differentiation of x² w.r.t t?

If 100g of steak equals 174cals, 12g fat, 21g protein.

How much calories using that chart, would be in 122g of steak and how much protein aswell?

More specifically what's the formula used to find that number? Thats really what i want to know. So I can do it myself.

I'm really bad at maths and neglected it too long but now once I know a formula I will not forget it.

I don't even know what to google to find that formula. Or equation.

The resultant matrix of the product of any 5 × 3 matrix and any another 3 x 5 matrix contains a variable entry x in exactly two places (positions) . If D(x) is the determinant of the resultant matrix of the product, such that D(0) = 1, D(-1) = 1 and D(2) = 7. Then

A D(1) = 3

B D(-3) = 7

C D(-2) = 3

D D(4) = 20

Keeping in mind that this question came in a test and you only have 6-7 mins per question to solve and your "working" isnt necessary only the final solution

Thanks for your responses in advance

Long story short, I started college recently and bought a TI graphical calculator and it came with so many features(I am 32 years old, so I am starting college a bit late hence why I am impressed, as in my time they were way more basic), the bloody thing can even run Python.

Hi I'm a future maths student in a french college and I'm looking for recommendations for tablets and maybe note taking apps ? What's better between Samsung and Apple as an Android user akso any tips in terms of using note apps with graphs or if laptops are better ? lmk what you use ! Thank you !!
