Question

vector{3,4,5}, how to count the vector length? And the sequences of the number represent x,z,y axis or wat?

Answer 1

yeah d given vector means :
3i + 4j + 5k

Answer 2

wat does i ,j and k mean?

Answer 3

the magnitude of x y and z axis...

Answer 4

so in my case x=3,z=4 and y=5? and how do u count the vector length?

Answer 5

nup...x=3 y=4 n z=5

Answer 6

Vector length
|(3,4,5)| = sqrt(3^2+4^2+5^2)=sqrt(9+16+25)=sqrt(50)=5sqrt(2)

Answer 7

ty guys ^^

Answer 8

one more thing, if vector{3,4,5} represent a rectangle in x,y,x, wat about vector{3,4,5,6}? Wat does the 6 mean? and any brief idea about how the shape is?

Answer 9

Unfortunately there is no visual image of a 4 dimensional object.
Usually the fourth dimension is time.

Answer 10

Some mathematicians describe the object in four dimensions as a hypercube, but we cannot have a hypercube physically.

Answer 11

vector can have infinity of variable in it?
