    Two vectors parallel to V are Image Upload
  4. How can a Vector be Orthogonal to another?
    Two vectors can be Orthogonal if and only if U⋅V = 0
  5. What are the two forms of the DOT product?
    • Image Upload

  6. What are the properties of the DOT Product?
    • U⋅V = V⋅U  Commutative property
    • C(U⋅V) = (CU)⋅V = U⋅(CV)  Associative property
    • U⋅(V+W) = U⋅V+U⋅W  Distributive property
