Study GuideTrigonometryβVectors1.The Rectangular Coordinate SystemFigure 1 Vectors drawn on a plane.In this chapter, we focus onvectors in a two-dimensional coordinate plane. The same ideas canbe extended to higher dimensions later, but for now, weβll keep everything in 2D to make the conceptsclear.1.1Vectors and Standard PositionAvectorπ΄π΅βββββrepresents bothmagnitude (length)anddirection.If a vectorπ΄π΅βββββis moved so that itsstarting point is at the origin, it is said to be instandardposition.When a vector (ππβββββ) starts at the origin and has thesame direction and magnitudeas (π΄π΅βββββ), it iscalled thestandard vectorfor (π΄π΅βββββ).You may also hear a standard vector called a:β’position vectorβ’radius vectorPreview Mode
