  1. Unit 5: Non-Cartesian Functions LG 5-1: Vector Functions (quiz 10/14) LG 5-2: Parametric Functions (quiz 10/16) LG 5-3: Polar Functions (quiz 10/18) TEST 10/21

  2. Magnitude : size/length • Direction: direction from one place to another (has 2 parts – an angle and a cardinal direction) The notation of a vector is a single letter in bold (v or u, etc)or a single letter with an arrow on top A Vector is a directed line segment that has two and only two defining characteristics:

  3. Vectors are made up of the Horizontal (x) and Vertical (y) Components Express the vector coordinates below as ordered pairs in simplest radical form. Components

  4. Find the horizontal and vertical components of the vector:

  5. Find the horizontal and vertical components of the vector:

  6. If a position vector has length 8 cm and direction 60°SW, then find the horizontal & vertical components.

  7. Find the magnitude and direction of the vector: v= 2, 3

  8. To add vectors in component form, just add the horizontal components and the vertical components. To add vectors graphically, just play “follow the leader.” Then draw a new vector from the start of the first to the end of the second. The new vector is called the resultantor displacement vector.
