Question

encontre um vetor unitário na direção e sentido de v= (1,2,3).​

Answer 1

$\Large\boxed{\begin{array}{l}\sf\overrightarrow{\sf v}=(1,2,3)\\\sf |\overrightarrow{\sf v}|=\sqrt{1^2+2^2+3^2}\\\sf|\overrightarrow{\sf v}|=\sqrt{1+4+9}\\\sf |\overrightarrow{\sf v}|=\sqrt{14}\\\sf \overrightarrow{\sf u}=\bigg(\dfrac{1}{\sqrt{14}},\dfrac{2}{\sqrt{14}},\dfrac{3}{\sqrt{14}}\bigg)\end{array}}$
