Page 1: Vector Basics and Calculations
This page introduces fundamental vector concepts and calculations in three-dimensional space. The content focuses on displacement vectors, position vectors, and basic vector operations.
Definition: A vector's magnitude |a| is calculated using the formula √a12+a22+a32 for a vector a = a1,a2,a3.
Example: For vector addition AB = 2,1,1 + 1,0,0 = 3,1,1, showing how consecutive displacements combine.
Highlight: Vector coordinates can be determined from the coordinates of two points Aa1,a2,a3 and Bb1,b2,b3 using the formula AB = b1−a1,b2−a2,b3−a3.
Vocabulary: The term "Betrag" magnitude refers to the length of a vector and is denoted by |a| for a vector a.
