Sir, Am not sure of some of them, could u plz help me? 1. Let e1 and e2 be the angles made by vector A and vector -A with the positive x-axis. Show that tan e1 = tan e2. Thus, giving tan e does not uniquely determine the direction of vector A. -- the part about tan e is not clear. 2. Is it possible to add two vectors of unequal magnitudes and get zero? Is it possible to add three vectors of equal magnitudes and get zero? Thnks in advance. Neeta
