savvy · Answer

dat kind of a notation

anonymous · Answer

Ohh, no point of reference for that notation, will the vectors v = (-1,1,1) and w = (1,0,-1) help?

savvy · Answer

Whenever u are given a vector like this:
v = (a,b,c)

the reference is always assumed to be the Origin (0,0,0).

nw can u tell me..??

anonymous · Answer

From that, its "u = 2i -1j +0k" it looks like

savvy · Answer

correct..!!

anonymous · Answer

Sorry, never did it in that notation

savvy · Answer

nw u knw hw to find the unit vector of the given vector..??

anonymous · Answer

Have its norm equal one?

anonymous · Answer

vector divided by norm!!

anonymous · Answer

What about the parallel part?

savvy · Answer

see, it means that vector,
u = 2i - 1j + 0k

is made when we move 2units on +ve x-axis, 1unit on -ve y-axis and 0units on z-axis.....
