In the Solve It, the Coast Guard had to know both distance and direction to rescue the sailor.
Essential Understanding A vector is a mathematical object that has both magnitude (size) and direction.
Take Note Key Concept: Vectors in Two Dimensions
A vector has magnitude and direction. You can describe a vector as a directed line segment with initial and terminal points. Two such segments with the same magnitude and direction represent the same vector.
represent the same vector.
A vector has both magnitude and direction. You often use an arrow to represent a vector. The magnitude of a vector v is the length of the arrow. You can denote it as | v |. You show the direction of the vector by the initial point and the terminal point of the arrow.
