ocr: The 1x2 vector A=[4: 2] can be thought of as representing anarrow in the coordinate plane. The arrow priginates at (0,0) and cerminates at the point(4,2). (12,6) Multiplying the vector A=[42] by3: stretches it: S0 thatit appears longer: 3A =314 - 2]=[126] Yiew scaling by: 03 l - 112 - I Scaling a Vector
