confused on how to solve for x

[indigo stirrup]

you're on the right track.

x=2π+5π/6

x=5π/6+12π/6=17π/6

[limpid tinsel]

Yes now I understand

@indigo stirrup can I ask for your assistance ?

[copper quarry]

what do you need help with?

[limpid tinsel]

I’m confused

How do I begin graphing it?

[limber dawn]

BIDMAS

[limpid tinsel]

What’s BIDMAS?

[limber dawn]

Brackets first indices second division multiply add then subtract

so first do the brackets

which means shift it to the right by 5pi/6

[limpid tinsel]

So that’s the phase shift?

[limber dawn]

then there is a stretch in the y axis by scale factor 3

yes

[limpid tinsel]

So phase shift is period/4

[limber dawn]

depends on the period of sin theta

which is 2pi

im not sure what u mean period /4

[limpid tinsel]

Alright how fo I start graphing?

Formula for phase shift

[limber dawn]

draw out sin theta

let me use x instead of theta

[limpid tinsel]

Yea

[limber dawn]

sin(x) = f(x) then sin(x-5pi/6) =f(x-5pi/6) then u do 3f(x-5pi/6) = 3sin(x-5pi/6)

[limber dawn]

yes

first step

[limpid tinsel]

I understand how to do that but I’m confused on how I shift 5pi/6 on the graph

[limpid tinsel]

Second step the amplitude is 3?

[limber dawn]

yes

amplitude + or - 3

because there is the -ve

shifting the graph right 5pi/6 same as shifting by 150 degrees to right

[limpid tinsel]

-ve is what?

[limber dawn]

negative

-1 and 1 is the range of the sin (x)

[limpid tinsel]

Yes can’t I just turn pi/2 to a common denominator of 6 which would make graphing easier

[limpid tinsel]

Yes

[limber dawn]

sure

do whatever can get u to the same answer

[limpid tinsel]

Meant to write pi/2= 6

[limpid tinsel]

Do I do that for all of them?

[limber dawn]

ur formula is confusing me i cant lie

but i think it could work

graph it on desmos

check if they are the same

as ur answer

[limpid tinsel]

Which one?

[limber dawn]

idk why u cant just shift by 5pi/6

150 degrees

[limpid tinsel]

My point is because I don’t know how to do that

[limpid tinsel]

I don’t know how

@limber dawn this correct? I found this

[limpid tinsel]

Phase shifting

[open oar]

.close

[limpid tinsel]

Huh??!?

[carmine flame]

Why are you trying to close this, it isn't your channel?

[limpid tinsel]

Thanks

Do I be patient?

[carmine flame]

yes

[limpid tinsel]

Alright 🙏

[limpid tinsel]

Is there a way to push it up
