Exercise · ZW-GRAM-SCHMIDT-PROCESS-003 · ★☆☆ Basic

Apply Gram–Schmidt to \(v_1=(1,-1)\), \(v_2=(2,0)\). What is \(w_2\)?

Choose one option.

Show answer
  • A. \((1,1)\)

Explanation

\(\frac{v_2\cdot w_1}{w_1\cdot w_1}=\frac22=1\), so \(w_2=(2,0)-(1,-1)=(1,1)\).

Review the concept: Gram–Schmidt process

A procedure that turns linearly independent vectors into an orthogonal list spanning the same subspace, by subtracting from each one its projections onto the previous ones.

\[w_k=v_k-\sum_{j
