ollowing rule forsubtracting one vector from an-other. In order to subtract one vectorfrom another reverse the one to hesubtracted and add it to the othervector. It is evident from Fig. 7 thatthe sum and the difference of two vectors form the diagonalsof the parallelogram determined by them.… … ANALYTICAL MECHANICS e2 = a + b + 2ab cos (j> = (10cm.)+(10cm.)2 + 2xl0cm.
