Verify that the set {(1,1,-2), (1,0, -1), (0,0,1)} is a basis for R Use Gram-Schmidt process to obtain an orthonormal basis. Write the vector (3,2,1)

Verify that the set {(1,1,-2), (1,0, -1), (0,0,1)} is a basis for R³ Use Gram-Schmidt process to obtain an orthonormal basis. Write the vector (3,2,1) as a linear combination of the vectors of this basis
