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 A(a₁,a₂,a₃) and B(b₁,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.
