Question

Ifi, j and k are unit vectors along x, y and z-axes respectively, the angle 0 between the
vector i- j + k and vector i is given by
​

Answer 1

Answer:

If i , j, and k represent unit vectors along the x , y and z - axis respectively , then the angle theta between the vectors i + j +k and i + j is equal to. Angle between 2 vectors is given cosα=i+j+k*i+j/√3√2=2/√6. Therefore α=cos inverse 2/√6.13-Jul-2018
