Exercise · ZW-GRAM-SCHMIDT-PROCESS-002 · ★☆☆ Basic
Apply Gram–Schmidt to \(v_1=(2,0)\), \(v_2=(3,4)\). What is \(w_2\)?
Choose one option.
Show answer
- C. \((0,4)\)
Explanation
Since \(\operatorname{proj}_{w_1}v_2=\frac{6}{4}(2,0)=(3,0)\), we get \(w_2=(3,4)-(3,0)=(0,4)\).
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
