ok i need to learn from the ABC for the concept!!!

partial too

depending how the waves interacted and waves can vary in energy too

but not all waves are the same nor collide in two manners only

could you please do a quick drawing of at least one of the examples?!?!!??!

any idea????????????????

I know this is generally more complex, but do they maybe just want you to add/subtract here?

do you still need help?

yus please!!

is it that same picture up at the top

can you please just do one question in drawing?!?!?!!? i'll do the rest.

um okay so its not exactly the crests that are combines its all the heights everywhere

interesting please go on!!!

|dw:1436150952876:dw|

in this case it'll be zero since A = highest - lowest /2

|dw:1436151013791:dw|

how tho?????? :O

okay what we do is look at every x values and add the 2 heights there

ok so do we come up with our own numbers here to calculate eveything

|dw:1436151217242:dw|

brb

ok back

Awwwnnnn!!!! |dw:1436162165903:dw|

how come yours is different from the picture

ok assume that the rectangle is touching the sin wave...sorry my bad.

|dw:1436151592824:dw|

we add 1 to everywhere on that wave

ok so to do my calculations, do i just make up my own numbers, i mean height

ill draw on the pic

ok please slow down for a sec.

http://prntscr.com/7pad48

ok what

well they gave u only pictures so answer with a picture

and please tell me the main rule/ recipe

but the picture is not on scale.

so

ok so that means we don't need to draw it on the graph paper????

i dont know

can you solce without the need of graph paper????

solve

okay main thing is
the form is this
f(x)= k + k*sin(x)

ok

you are adding to like a sin(x) looking wave

its not really a sine wave, just making that up

ok so how do we utilize the equation to find the displaceent

hi

hi :)

lol

lets start over

please!!!

:)

|dw:1436152421672:dw|

ok.

|dw:1436152449162:dw|

ok i see.

|dw:1436152521293:dw|

but how do you know how high is that???? since there are no numbers given

we dont

ok cool....next!!!

ok so you brought everything on the positive side of the equilibrium....nice!!

by adding 1

there are no numbers

ok i see.

ok what's next.

u tell me

honestly if i knew i'dn't be here. but give me some time to take a guess!!!

you add crest of both waves!!!

the question is done

but the question asks me to "determine the resultant wave" so what do i say?!?!?!?

|dw:1436152891797:dw|

btw how would the final wave look like if we're to actually draw the resultant wave!!

what happened to the green magenta rectangle, weren't you suppose to add that height as well.

because the rule says, when two waves collide, they make constructive wave!!!

|dw:1436153051159:dw|

OMG i kinda understood what you did there.....!!!

ok i got it......!!!

ok so what would happen to the first one?!???!

ill give u a problem do it to the best of your ability

so for the first question do you just stack the inner black box on top of the dotted box?!?!?!

|dw:1436153397371:dw|

what is the result of these 2?

wait is that a V or a triangle?!?!?!?

okay try another one

|dw:1436153559275:dw|

|dw:1436153620648:dw|

|dw:1436153640721:dw|

hold on damn it... let me think :"D LOL

|dw:1436164670586:dw|
you add 1

|dw:1436164695260:dw|you add 1 LOL

|dw:1436164718280:dw|you add 1
