2.1. Show that <x, y>=x1y1+2x2y2+x3y3, x=⎣⎡x1x2x3⎦⎤ ,y=⎣⎡y1y2y3⎦⎤∈ R3
2.2. Are the vectors ⎣⎡111⎦⎤, ⎣⎡11−1⎦⎤, ⎣⎡1−1−1⎦⎤ Linearly independent?
2.3. Apply the Grem-Schmidt process to the following subset of R3 ⎣⎡111⎦⎤, ⎣⎡11−1⎦⎤, ⎣⎡1−1−1⎦⎤ to find an orthogonal basis with the inner product defined in 2.1. for the span of this subset

2.
∣∣11111−11−1−1∣∣=−2−2=−4
Since determinant is not equal zero, the vectors are linearly independent.
