trigonometry

[placid schooner]

Is what I’ve done so far right

Idk how to make x the subject

It always confuses me

[fiery vale]

you are doing it right

[placid schooner]

Ok

But how do I make d the subject

X

[fiery vale]

now do you know the value of cos 45?

[placid schooner]

i normally cross multiply it

[placid schooner]

U don’t need to tbh

[fiery vale]

but x= 1.3*cos 45

[placid schooner]

oh ok

Is there a trick toy jave btw

You have*

Cuz whenever I wanna make x or whatever the subject

It always confuses me

[fiery vale]

you just take x on one side and constants on the other side

like here

[placid schooner]

Oh right

[fiery vale]

I multiplied both sides by 1.3

[placid schooner]

Yeah

Is the final answer 0.92m btw

Nearest 2 dp

[fiery vale]

1.3 * cos45=x * 1 .3/1.3

[placid schooner]

I think I’ve understood what you’ve said

[placid schooner]

Yes

Btw u from India

[fiery vale]

1.3/1.3 is 1

yes

[placid schooner]

Same

Which state

[fiery vale]

to much detail

[placid schooner]

K

I’m from Kerala

Down south

[fiery vale]

cool

[fiery vale]

because they focus on education

[placid schooner]

True we’ve got the highest percent literacy rate in india I believe

Like 90 somet prevent

[fiery vale]

this is inverse trigo right?

[placid schooner]

Yes

Cuz we finding angle

Am I right

[fiery vale]

I don't know inverse trigo

[placid schooner]

Do you not?!

[leaden sage]

same

[fiery vale]

yeah I know a lot of other stuff though

[leaden sage]

idk if its that x, but cos inverse part is correct

[fiery vale]

like solution of triangle

SOT=pain

[placid schooner]

mk

What’s SOT

[fiery vale]

I don't recommend SOT

[fiery vale]

solution of triangle

[placid schooner]

Oh

[fiery vale]

sine rule and cosine rule and stuff

[placid schooner]

I use SOHCAHTOA

[placid schooner]

Right..

[fiery vale]

I've solved so much trigo I don't need any tricks to remember that

[placid schooner]

What year u in

[placid schooner]

Nice

[fiery vale]

you?

[placid schooner]

U gonna do a level maths?

[placid schooner]

8

[fiery vale]

they teach you trigonometry in 8th?

[placid schooner]

no it’s cuz I have private tuition

[fiery vale]

oh

[placid schooner]

So I learnt it from there

[fiery vale]

understandable

[placid schooner]
