# A vector <span la

Given that,

Magnitude of = 2√3 Also, given that

Vector is equally inclined to the three axes.

This means, direction cosines of the unit vector will be same. The direction cosines are (l, m, n).

l = m = n

The direction cosines of a vector are simply the cosines of the angles between the vector and the three coordinate axes.

We know the relationship between direction cosines is,

l2 + m2 + n2 = 1

l2 + l2 + l2 = 1 [ l = m = n]

3.l2 = 1  Also, we know that is represented in terms of direction cosines as,  We are familiar with the formula, To find , Substituting values of and .   Thus, the value of is .
