Product of vectors

The vectors and scalar quantity of two multify. The vectors are magnitude direction and the sclary are distance. The vectors are distance between angle and the vectors is know as an vectors. 



Questions


1.find  the angle between the vectors ī+2j′+3ō and 3ō+j“+2ō.

Solution:

          Let ā =ī+2j′+3ō  and  b = 3ō+j“+2ō

          And ø be the angle between 

them (i, e) (ā, b) 

       Then  cos ø  = ā. b/|ā||b|

= (ī+2j′+3ō )(3ō+j“+2ō) /|ī+2j′

+3ō||3ō+j“+2ō |
   
               = (3-2+4) /√1+4+9.√9+1+4
               = 7/14  = 1/2

             Cos ø = 1/2
    
              ø = π/3.
