Wired Faculty App

Find values of x for which straight x space open parentheses straight i with hat on top space plus space straight j with hat on top space plus space straight k with hat on top close parentheses is a unit vector. 

Solution

Let straight a with rightwards arrow on top space equals space straight x space left parenthesis straight i with hat on top space plus space straight j with hat on top space plus space straight k with hat on top right parenthesis space equals space straight x space straight i with hat on top space plus space straight x space straight j with hat on top space plus space straight x space straight k with hat on top
Since straight a with rightwards arrow on top is a unit vector
