Calculus III

  1. What is a position Vector?
    A vector that's tail is at the origin and Head is at some point (V1, V2)
  2. What is the Position Vector of points Q(-2,1) and U(6,5)?
    The position vector is Image Upload 1 with the tail at the origin (0,0) and head at (8,4)
  3. Find two vectors that are both parallel and 3times the magnitude/length of V. V=<V1,V2>
    Two vectors parallel to V are Image Upload 2
  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 3
    • Image Upload 4
  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
  7. 1. If you have projection U onto V (ProjVU) how would you represent the length of the projection?
    2. What would the vector created by the projection then be represented by? (Magnitude ⋅ Direction)
    1.  Image Upload 5 also known as the scaler comp

    • 2. Image Upload 6
    • NOTE: may need to sub out Image Upload 7 using DOT product equations.
