SHOW AND EXPLAIN ME THE ADDATION IN VECTORS

Its very easy respective elements are added:

like consider two matrices of 3*3. 

1 2 3              3 2 1

4 5 6    and   6 5 4

7 8 9             9 8 7

Then there add. will be:

4 4 4

10 10 10 

16 16 16. 

I hope u got it . Add first first , 2nd 2nd, 3rd 3rd and so on.

'

Its very easy.

Suppose the vectors are given in their resolved forms like 2i+3j+5k and 1i+2j+4k

Just add the x,y and z components like this>>>

(2+1)i+(3+2)j+(5+4)k=3i+5j+9k this is your resultant vector.

its magnitude is sq.root of 9+25+81.

Or u can add the vectors graphically.Just position them head to tail and the resutant

will be from the empty tail to empty head.

IF A = ai+bj+ck and B = xi+yj+zk  where i,j,k represent unit vectors along x, y and z direction respectively

then

(A+B) = (a+x)i + (b+y)j + (c+z)k

magnitube of (A+B), IA+BI = (IAI² + IBI² + 2ABcos theta)^1/2

i hope that u got a clear idea about addition of vectors...........
