Question: In Exercises, use the given non orthogonal basis for vectors in R3 to find an equivalent orthogonal basis by means of the Gram-Schmidt orthogonaizatlon process.
Exercise: 1. a1 = i + 2j + k, a2 = i - j, a3 = 2j - k.
2. a1= j + 3k, a2 = i + j - k, a3 = i + 2k.
3. a1 = 2i + j, a2 = 2j + k, a3 = k.
