What is the unit vector in direction of vector $straight P with rightwards arrow on top space equals space minus 3 straight i with hat on top plus 2 straight j with hat on top plus 5 straight k with hat on top$ ?

Solution

Unit vector in direction of $straight P with rightwards arrow on top$ = $fraction numerator straight P with rightwards harpoon with barb upwards on top over denominator vertical line straight P with rightwards harpoon with barb upwards on top vertical line end fraction$
Therefore, we get,
$P with hat on top space equals space fraction numerator 1 over denominator square root of 38 end fraction open parentheses negative 3 straight i with hat on top plus 2 straight j with hat on top plus 5 straight k with hat on top close parentheses$
