A Traveling wave

OpenStudy (babynini):

I know right. Sentence fragments ftw.

OpenStudy (babynini):

I'm alright D: haven't really worked on any of it today because of mothers day o.0

OpenStudy (babynini):

@acxbox22 help? :)

OpenStudy (babynini):

so I think part a) y=5sin3(x- b) is velocity the same thing as phase shift? (in other words does velocity go where b is?

OpenStudy (babynini):

@zepdrix

zepdrix (zepdrix):

uhhhh i dunno +__+ tired... thinkinggg

OpenStudy (babynini):

aw, ok :) #exhaustion.

OpenStudy (babynini):

Dude, i know that feeling though. When I have just got on openstudy and someone tags me in a question and i'm already brain dead and don't feel much like being helpful D: you're all good.

zepdrix (zepdrix):

lol XD

OpenStudy (babynini):

using the formula y=a sin k(x-vt) [is that even correct? o_o) This is what I got. for part b) of the question.

zepdrix (zepdrix):

Hmm I'm not familiar with traveling wave... this is the equation that I'm seeing when I google it: \(\Large\rm y=A\sin\left[\frac{2\pi}{P}\left(x-v t\right)\right]\) Where: `A is amplitude` `P is period` `v is velocity` Your formula looks the same as mine, ok good.

zepdrix (zepdrix):

\[\Large\rm y=5\sin\left[\frac{2\pi}{(2\pi/3)}(x-0.5t)\right]\]Uhhh something like that? 0_O

zepdrix (zepdrix):

Oh yes yes you simplified the b term, niceeee.

zepdrix (zepdrix):

We can see the wave traveling to the right :D Ahh now it's making sense

OpenStudy (babynini):

hm yeah the period is found by doing 2pi/k where k is the period. so since they gave me period = 2pi/3 I just took the 3 to equal period. Does that make sense?

OpenStudy (babynini):

haha yes! it's like magic!

zepdrix (zepdrix):

So what do you need help with then!? >:U Looks like you've got it figured out :D lol

OpenStudy (babynini):

I didn't know that I had it right! I thought i had it wrong lol xD you know when you think you've got it figured out but then it turns out it's all messed up? Math is sketchy like that.

OpenStudy (babynini):

Wait so the v in (x-vt) does equal velocity? I can just plug it in?

zepdrix (zepdrix):

I dunnoooo >.< I'll say yes. But I don't know. Maybe tag someone else :D lol

zepdrix (zepdrix):

imma go get some foods <.< deal with it

OpenStudy (babynini):

oh how nice of you. haha thanks so much. Have a fun time eating xD

OpenStudy (babynini):

@Nnesha do you know how to do these??

OpenStudy (babynini):

@jim_thompson5910 I know you just got on. But can you just check this real quick? :) it's all done, just needs to be reviewed.

jimthompson5910 (jim_thompson5910):

Yeah I'm finding the same formula more or less http://hyperphysics.phy-astr.gsu.edu/hbase/waves/wavsol.html unfortunately I don't know why there are two input variables (x and t).
