This document covers key concepts in vector mathematics, including coordinate systems, parallelograms, reflections, parallel lines, and the centroid of a triangle. It provides detailed explanations and examples for solving vector problems in 3D space. The material is suitable for advanced high school or early university-level mathematics courses.
Key points:
• Plotting points and shapes in 3D coordinate systems
• Calculating parallel and perpendicular vectors
• Finding reflection points across planes
• Deriving parametric equations for lines
• Determining if points lie on given lines
• Proving when lines are parallel
• Calculating the centroid (center of mass) of a triangle
Highlight: The document emphasizes showing clear calculation steps and explaining reasoning, which is crucial for exam preparation.
Vocabulary: Important terms include parametric equations, direction vectors, position vectors, and centroid.
