Day 32: Linear Algebra

Today:

• Homework returned:
  • Section 4.3 homework
    • 11 -- a basis is a set. Use set notation: {v₁,v₂}
    • 20 -- you can do this one by inspection: but you do have to check for independence of the two vectors you choose for your basis.
  • Section 4.4 homework
    • 16 - T, F, T

• Section 4.5 homework due
