Vectors
Study Guide Overview
This study guide covers vectors in AP Precalculus, including their definition (magnitude and direction), representation (2D components, trigonometric form, zero vector), operations (scalar multiplication, vector addition, dot product), and unit vectors (standard unit vectors i and j, linear combinations). It also reviews the Law of Sines and Law of Cosines for solving triangles formed by vectors and provides practice questions focusing on vector components, operations, unit vectors, and applying the Laws of Sines and Cosines.
