Basics of Vector Calculus

Find the unit vector in the direction of vector $\vec{A}/$

$\vec{A}=3{{\hat{a}}_{x}}+4{{\hat{a}}_{y}}+5{{\hat{a}}_{z}}/$

$\frac{4{{{\hat{a}}}_{x}}+5{{{\hat{a}}}_{y}}+3{{{\hat{a}}}_{z}}}{\sqrt{50}}/$

$\frac{3{{{\hat{a}}}_{x}}+4{{{\hat{a}}}_{y}}+5{{{\hat{a}}}_{z}}}{\sqrt{50}}/$

$\frac{5{{{\hat{a}}}_{x}}+3{{{\hat{a}}}_{y}}+4{{{\hat{a}}}_{z}}}{\sqrt{50}}/$

$\frac{4{{{\hat{a}}}_{x}}+3{{{\hat{a}}}_{y}}+5{{{\hat{a}}}_{z}}}{\sqrt{50}}/$
