Re ie ray? Se ot dee ea BY OD APUCHILILICS., , Like. goes, , Representation of vectors, A vector is represented by a directed line se gment whose end points, are designated as initial and terminal points. The length of the segment, , oives the magnitude of the vector,, oO, , Thus AB denotes the line segment bounded by the points ‘A’ and, ‘B’ and having ‘A’ as the initial point and ‘B’ as the, , rerminal point. With each vector AB, we associate |, two measures, the distance between ‘A’ and ‘B’ and, , the direction from ‘A’ to ‘B’. AB can be considered, as a quantity having length arid direction ‘A’ is also, , called origin and ‘B’ the terminus. AB is read as :, vector AB and can be represented by AB or AB (bold), jts magnitude is represented by AB or AB., , 0
