Linear Algebra

How to solve

To draw u + v, place the tail of v at the head of u. The sum runs from the original tail to the final head.

Steps

  1. Add corresponding components.
  2. Locate the final head in the diagram.
  3. Read the requested coordinate of u + v.

Example

u = ⟨2, 1⟩ and v = ⟨−1, 3⟩.

  1. u + v = ⟨2 − 1, 1 + 3⟩.
  2. u + v = ⟨1, 4⟩.

Answer: 1 or 4 depending on the requested component
