Question

Fill in the blanks:

For any vectors ,$\mathit{u}\mathbf{.}\mathit{v}\mathbf{=}\mathit{\_}\mathit{\_}\mathit{\_}\mathit{\_}\mathit{\_}\mathit{\_}\mathit{\_}\mathit{\_}\mathit{\_}\mathit{\_}$

Short answer

The required answer is$u_1{v}_1+u_2{v}_2+u_3{v}_3$

Step-by-step solution

Given information

Two vectors

Filling in the blank

As per the dot product formula:

$\mathit{u}.\mathit{v}=u_1{v}_1+u_2{v}_2+u_3{v}_3$
