math idk:)

[thorn lava]

To find x, use cosine
cos46°=x/13.4
x=13.4 * cos46
x≈9.308

[real thorn]

i love u

solved

[cyan plank]

what you need to do

get x?

do u have more

[real thorn]

i have akit'

alot

is my wh

[tacit nest]

lmao

[cyan plank]

can you wait until I get my calculator

[native cloud]

wrong ig

[native cloud]

cos(theta) = adjacent/hypotenuse

[thorn lava]

OH RIGHT

MY BAS

MY BAD

[real thorn]

damnnnnn

[thorn lava]

cos46=x/13.4

[native cloud]

9.308 is the answer

[thorn lava]

x=9.31

😭😭I'm so sorry @real thorn

[real thorn]

i have a cal on me dw

[cyan plank]

is it
x=11.7×sin63°≈10.42

[native cloud]

10.42 km

it's cool that u guys use calculator for the trig answers

[real thorn]

`who doesnt

broo

[cyan plank]

Bro I aint gonna calculate sinus and tangens

[native cloud]

me and everyone in my country

[real thorn]

ongg bro

[cyan plank]

that tales like half an hour

[real thorn]

wait what

you do?

[cyan plank]

I do too, but not sin and cos and tan

[native cloud]

arent allowed to use calc anywhere

we use the derivative to calculate the change in small angles (also we use radian not degrees)

you will learn it later

[thorn lava]

π/180

if I'm not wrong💀

[native cloud]

yeah, standard conversion

[cyan plank]

can you teach me

[native cloud]

you will learn it later for sure if u take math later on in studies

it's awesome

[cyan plank]

I will if I get into thats chool next year

[native cloud]

30 degrees -> pi/6 radians

[cyan plank]

but can u teach me now

[native cloud]

take a trig course online

[cyan plank]

that cost money

i dont have money

[native cloud]

look for free one

[cyan plank]

I bought my first calculator 2 week ago

[native cloud]

TI-??

[cyan plank]

What s a ti

[native cloud]

texas instruments

[cyan plank]

What is that

[native cloud]

the one who makes calculators

company

which brand u got

[cyan plank]

no I have Citizen

[native cloud]

hm

[cyan plank]

2 row

[native cloud]

country-specific??

[cyan plank]

everyone here has citizen

even teacher ordered citizen

[native cloud]

ok, @real thorn your questions are solved ig

[cyan plank]

I used teachers calculator until now

rnvy do u have more

[cyan plank]

just give me algrorythm

[native cloud]

good for you, we here dont use it much

[cyan plank]

WhAt

[native cloud]

wait

[cyan plank]

Maybe give an example too

[real thorn]

hongkong

[native cloud]

angle in radian = (angle in degree) * pi/180

like 30 degrees * pi/180 = pi/6 radian

[cyan plank]

OH

[native cloud]

and then we use pi/6 in the arguments for the trig functions

[native cloud]

time to make this thread solved

[real thorn]

ok

[cyan plank]

so 60 degree × π/180 = π/3 radian?

i dont tjink i get it

[native cloud]

yeah

[cyan plank]

oh

i think i get it

[native cloud]

for now yeah

simple calculations

[cyan plank]

but what do i do with radian

how is that better than degree

[native cloud]

a whole lot more stuff than degrees

[native cloud]

it makes the length of the arc comparable to the angle subtended

ig

[cyan plank]

what is arc and subtended

Do you have international term

[native cloud]

lol, you dont have an idea about circles and trignometry

that;s why wait

and see for yourself ltaer

later

[cyan plank]

What do you mean

[native cloud]

in advance math courses, everybody uses radian

[cyan plank]

I do trigonometry

but not the very hard one

[native cloud]

take more classes, advance classes

[native cloud]

then you are stucked with degree system for now

[cyan plank]

can you give me an example of a advanced problem in trigometry

[native cloud]

uhh

let me check

like find the general soluton for the equation tan^2(2x) = 1

still not that advance but comparable, here u start learning

[cyan plank]

okay

[native cloud]

2sin^2(x) = 3cos(x), find the value of x

here we dont use degree measures at all

[cyan plank]

really

okay

so I use the pi thing

what grade do you start doing this

@native cloud ä

[native cloud]

for me I started in grade 11
