argand diagrams

[frosty umbra]

can someone explain the segment area part thats where im getting lost

[somber delta]

have u done radians?

in normal maths

[frosty umbra]

nope

[somber delta]

you need that knoweldge for this q

[frosty umbra]

well i know enough i think

180 degrees is pi

[somber delta]

theres a few formulae for working out sector and segment area

[frosty umbra]

im sure u could do with as fm knowledge

[somber delta]

i mean itd be very hard lemme try nd explain it

[frosty umbra]

i think i have an understanding

i could use 1/2 ab sin c

[somber delta]

yeah thats one part of it

[frosty umbra]

then find the area of the sector

so if 360 degrees is 2pi

then 2pi / 3 is 1/3rd of that?

do the formulas work the same as if i used degrees

for like area of sector

[somber delta]

yeah u jus need to convert as youve done

impressive

[frosty umbra]

so instead of using theta/360 x pi x r^2

its the angle/2pi x pi x r^2

[somber delta]

which simplifies nicely

to ½r²(theta)

which is one of the formulae in the radians chapter

the other is arclength which u could prolly also derive

[frosty umbra]

this is year 2 single maths?

[somber delta]

yeah

[frosty umbra]

should i learn it now or wait till i do it in school

[somber delta]

u definitely can learn it now

so why not

[frosty umbra]

ok

[somber delta]

you basc alr know it 🤣 but its good to make sure u know everything

[abstract vine]

Don’t need radians really for this

[whole thorn]

no need for radians

[frosty umbra]

yo why did u reply like 6 months after

[whole thorn]

oh shit

💀

[vast wolf]

100 percent edexecl

[whole thorn]

yes

why 100% edexcel

[vast wolf]

I just knew it was edexcel

I've seen too many edexcel questions and mark schemes

I'm traumatised by the font

It'll stay in my head forever

[whole thorn]

damn

[frosty umbra]

💀

[whole thorn]

no radiaaaans!

[frosty umbra]

yes mate

[modest phoenix]

😹

[frosty umbra]

wys bony

[modest phoenix]

What’s good champ u done any work today

I’m good

[abstract vine]

Why is this thread still up lmao

[whole thorn]

it must be

until @frosty umbra themselves decides to close it

i will ensure it is at the top

[frosty umbra]

😭

[whole thorn]

yes

no one will ever forget abt argand diagrams

[barren hamlet]

🤔

[vast wolf]

Hwat the fuck

[whole thorn]

basically a GCSE argand diagram q fr

[vast wolf]

yh tbf the coordinate geometry part doesnt seem too hard

like finding that right angle triangle

the lengths are no diff

[whole thorn]

yes

no new formulae either its just area of a triangle and area of a sector and stuff

[vast wolf]

but i js dont know what the question is asking or how how the domains work

[whole thorn]

oh LOL that should be fine

thats like

the easy part that might look harder than it is

[vast wolf]

Yh rs

like what the z, weird C, a and b + ci, d are

looks fun to solve though

might start learning it for fun sometime soon

i've done integration which was honestly super fun

but havent started binomials and argands yet

[whole thorn]

Yeah

[vast wolf]

been putting them off in favour of GCSE sciences

[whole thorn]

dayum

r u going into y11

[vast wolf]

yes

but tbf i do further maths so i know some of the y12 curriculum from that

matrices etc

3d coordinate geo

[whole thorn]

oooh i see thats cool

[vast wolf]

yh honestly a blessing

hopefully y12 is light for me so i can finish the y13 content ASAP

i want y13 to be a repeat of y11 where it's just constant revision and no learning of new content

though unfortunately i havent been able to cover the whole curriculum for GCSE sciences yet

hoping to finish it all by late october/early november

[whole thorn]

u gonna do a level maths in y12? or just learn all the content for a-level but not sit the actual exam

till y13

[vast wolf]

Not sit the exam, i dont see the benefit in that

im gonna have to sit my ucat and submit my epq as well

and also get ready for interview

so a whole a level to do would just be too much on my plate

[whole thorn]

oh yeah thats fair enough

[vast wolf]

esp considering i have to prelearn all of a level bio and chem content because the interviewers for camb are pretty cheeky

they ask some mean questions

[whole thorn]

damn

[vast wolf]

but yh Inshallah I will get into cambridge

Otherwise I wont really be too bummed since I wanna go to UCL'/Imperial anyway

[whole thorn]

same UCL & imperial sound dope

[whole thorn]

inshallah 🙏

[potent loom]

this question was painful

[frosty umbra]

damn u guys rlly wanna keep this thread alive

[vast wolf]

Poor guy 😭

[whole thorn]

yes

[potent loom]

😭

[vast wolf]

LET THE THREAD DIE HOLY SHIT 😭

I’M NOT FOLLOWING THIS BS ANYM

[barren hamlet]

nuh uh

[whole thorn]
