Graph the function.

OpenStudy (erinweeks):

\[y = |\cot \frac{ x }{ 4 } |\]

OpenStudy (erinweeks):

@jim_thompson5910 can you help?

OpenStudy (erinweeks):

@Hero ?

jimthompson5910 (jim_thompson5910):

to graph this, I recommend using geogebra

jimthompson5910 (jim_thompson5910):

do you have geogebra?

OpenStudy (erinweeks):

i have it but remember i dont know how to use it :/

jimthompson5910 (jim_thompson5910):

that's ok, I can help you with that

OpenStudy (erinweeks):

okay (:

jimthompson5910 (jim_thompson5910):

open up geogebra and tell me when it's done loading

OpenStudy (erinweeks):

its up!

jimthompson5910 (jim_thompson5910):

ok great

jimthompson5910 (jim_thompson5910):

in the input bar, type the following (without quotes) "cot(x/4)"

jimthompson5910 (jim_thompson5910):

then hit enter

jimthompson5910 (jim_thompson5910):

the graph of cot(x/4) would then pop up after hitting enter

OpenStudy (erinweeks):

i dont see a input bar

jimthompson5910 (jim_thompson5910):

at the bottom of the geogebra window

jimthompson5910 (jim_thompson5910):

it's a very long text field (long and skinny) where you can type in stuff, to the left of it says "input"

OpenStudy (erinweeks):

i see it lol

jimthompson5910 (jim_thompson5910):

that's great

OpenStudy (erinweeks):

okay i did it now is that my answer?

jimthompson5910 (jim_thompson5910):

yes it is

jimthompson5910 (jim_thompson5910):

those curves all together are the graph of cot(x/4)

jimthompson5910 (jim_thompson5910):

you can try to copy all that by hand on graph paper or you can export the image so it's professional and accurate looking

OpenStudy (erinweeks):

it doesnt look like any of my graphs

OpenStudy (erinweeks):

my graphs are in like pi?

jimthompson5910 (jim_thompson5910):

show me what you mean

OpenStudy (erinweeks):

here's my answer a

jimthompson5910 (jim_thompson5910):

ah ok, i see now

OpenStudy (erinweeks):

so it confuses me:/

jimthompson5910 (jim_thompson5910):

what do the other choices look like

OpenStudy (erinweeks):

B

OpenStudy (erinweeks):

answer C

OpenStudy (erinweeks):

answer d

jimthompson5910 (jim_thompson5910):

ok here's a better look at what the graph looks like

OpenStudy (erinweeks):

So its A or B?

OpenStudy (erinweeks):

i think its B?

jimthompson5910 (jim_thompson5910):

B is correct, nice job

OpenStudy (erinweeks):

thank youuu ((:
