VECTORS AND SCALARS: BASIC CONCEPTS Exercise 7.2 Solution : 1. For the arbitrary points A, B, C, D and E, and a single  vector which is equivalent to A:   DC + CB    = DB B:  CE + DC   = DE 2.  shows a cube. Let p =  AB, q =  AD and  r =  AE . Express the vectors representing  BD,  AC and  AG in terms of p, q and r. Consider the triangle ABD shown in Figure. We note that  BD represents the third  side of the triangle formed when AD are placed head to tail. Using the triangle law we find :                      AB + BD = AD               => BD = AD - AB                             = q - p Consider the triangle  ADC  shown in Figure. We note that  AD  represe...
