I have attached the assignment the one I wrote in the top is wrong, the right one is: f(x,y,z) = ((( x / ((1+z^2)*(x^2+y^2)),(y / ((1+z^2)*(x^2+y^2)),0)
F = i x-comp+ j y-comp + k z-comp ... most probably
what do you mean by comb?
I dont have to draw anything?
component ... this is going to be complicated figure.
I dont understand what component mean. How will the final result be like?
Im sorry Im not very good at English
in each point in 3-dimensional space put the value of that point, you get a vector ... and the set of such vectors in such point is a field ... try for one point
im afraid I still dont get it
f(x,y,z) = (x, x+y, x+y+z) --- for example let this be a function, your x-component is x, y component is x+y, and z component is x+y+z at point 0,0,0 you have 0i+0j+k0 = 0 do you have 0 vector a 0,0,0 at 1,1,1 you have 1i+2j+3k ... not dray it ... it's going to look like this
I have never seen an assignment like this regarding field lines. Usually I know how to solve them but this is completely different from what I useed to do
but how is it in my case?
draw at every point, you will get a field .... In your case it's going to be much work, i'm afraid ... the earlier example i provided was simple case
try putting values at few points like (0,0,0), (1,1,1) ... you will get the general picture
How do you know which points to use?
you can use any points. since it is going to be complicated, use such points so that your work will be simpler
okay i will try to generate using some software
Thank you very much.
I dont even understand this part: F = i x-comp+ j y-comp + k z-comp
your z-component is zero ... so i guess, you will get a field on xy plane
it's a vector notation (2,3,4) = 2i+3j+4k
oh i see that now
But what then?
okay, find the value at 1, 1, 1
If I take too much time will you be able to help me later?
not so sure .. i might not be online
Oo i got one example ... wait for a while
Im not going to be able to solve this.......
i am trying using a software
i shouldn't take long
I can wait
I appreciate your help very much
sorry didn't work for z=0
Oh my god
if you can make them flat ... i mean parallel to x,y axis --- from their point of origin ... you will have your answer
damn whoever coded this ... didn't code complete
that is the only part I know how to do now
yeah ... put value of x,y,z 1 1 1
Okay I get i1/5 + j1/5 + 0 ?
do you know how to plot this ?? |dw:1332842444812:dw|
No I really dont
Hehe it's hard to see what is happing in the drawing
I understand it has to be 3-dimensional but I dont know how to get the coordinates
AB is your vector ... it starts from 1,1,1 ... with 1/5 along x-axis and 1/5 along y axis
And do I just choose what I want like when I plottet (1,1,1) ?
wdy did you draw 3 vectors?
yeah ... more points you choose more abstruse and more better the picture
no it's just one vector ... two are to illustrate how it's components work ... and as you can see they are bidirectional
I dont understand that
and can I choose coordinates like (1,-1,-1)?
how can I find where the vector starts on the graph?
it starts form the point where you choose earlier
how do I find that point; 1/5,1/5,0?
in the graph you made, is the axis going up z?
Im sorry for all these stupid questions but Im lost
but how will the actual field lines look like? With all the arrows (vectors) I suppose we dont have the field lines yet
z axis is going up, and your coordinate was 1,1,1 not 1/5,1/5,0
What di I get if I use (1,1,-1)?
