Question

find the value of [i, j, k]

Answer 1

Answer:

1

Step-by-step explanation:

[ a, b, c ] refers to the scalar triple product. It is the dot/scalar product of vector c and vector (a x b).

Or, [ a , b, c ] = (a x b) . c

Thus,

[ i , j , k ] = (i x j).k

      = k.k        [ i x j = k ]

      = | k |²      

      = 1
