How to convert from V1,V2,V3 to E1,E2,E3

[SuperMiguel]

So a professor gives me 3 vectors U1, U2, U3 then asks me to calculate

1. Calculate the orthogonal basis vector v1,v2,v3
2. Calculate the Orthonormal basis vectors e1,e2,e3

How do i do question 2? how do i get the orthonormal basis from the orthogonal basis?

Reduce the magnitude of each of the vectors to one.; ie. e₁ = v₁/|v₁|
