i know the amplitude is 3 but how do i find the others by looking on te graph

|dw:1372972730730:dw|

|dw:1372972742833:dw|

|dw:1372972804524:dw|

so the period would be -pi minus pi?

period is the length between these 2 points

|dw:1372972988966:dw|

what is that length?

-pi/2 to pi/2?

that is the start and end points u are giving me for 1 oscillation
what is the length?

|dw:1372973050228:dw|

6?

|dw:1372973090009:dw|

|dw:1372973124432:dw|

|dw:1372973163758:dw|

oh 5 so i exclude my starting and ending point?

lemme ask you simpler question... what is this length|dw:1372973193523:dw|

you know pi is just a number right
is that what is confusing you
pi = 3.14159263.....

3.14159265*3

i dnt know why im not undertanding would it be -2? i did -pi/2-pie/2

okay can i ask you 1 thing

yea

|dw:1372973327455:dw|

ruler is 20 cm

yeah

whats the distance from the middle

to 20 cm

these are not trick questions lol

|dw:1372973442701:dw|

i would say 15 is b/w it ...

wut the...

okay a rule is 20 CM...

lol i dnt know

what is half of the rule distance?

okay maybe we need to work with smaller numbers...

|dw:1372973564661:dw|

do u know a site that has similar examples ?

what is the distance between point 1 and 2?

what is 1+1?

lol

okay so that means there was 1 added to 1

|dw:1372973646856:dw|

so that distance there is 1... DO YOU GET IT??

i think so

wait can you see my drawing?

yes

|dw:1372973792265:dw|

yay

so how long is this whole line?|dw:1372973851072:dw|

2 i think

amazing u are like a genius

|dw:1372973890765:dw|

lengths in between there?

lol um

im not sure i dnt wanna write the wrong thing

theres ur problem.. ur too afraid to do math

you cant learn like that... everyone will make mistakes, but they have to learn from it

yeah i know

|dw:1372974092155:dw|

now answer

lemme show it to you another way

|dw:1372974117812:dw|

|dw:1372974154511:dw|

do you agree is right?

yes

what is the total length of this line?

okay, so u see me writing from 0 to 2
or -1 to 1
they were both length 2

yeah

|dw:1372974249234:dw|

okay now

|dw:1372974271992:dw|

2?

okay let me rephrase question

|dw:1372974319201:dw|

....

|dw:1372974380394:dw|

|dw:1372974427613:dw|

|dw:1372974491987:dw|

3.14

|dw:1372974530003:dw|

...

what is the length of the left side

-3.14

length

can something be negative units long?

what is the size ? of that line

3.14

|dw:1372974670469:dw|

|dw:1372974677600:dw|

dan i dont want to take up your time...i better ask my techer in the morning

do u know what pi is

yes as a decimal 3.14

okay so...

|dw:1372974930747:dw|

length of this part?

3.14

or you can just say pi

yes

saying pi is the same as 3.14159...

|dw:1372974979657:dw|

length of left side?

yea i know

dont over think it...
get simple

-pi

... again..
can the size or length of something be negative?

no

can your leg be - 3.14 long?

if you measure your leg from top to bottom and then bottom to top will your answer change
