Web1 feb. 2015 · Just knowing that a 2 + b 2 + c 2 = 1 is not enough to determine the value of a b + b c + c a. For example, if a = b = 0 and c = 1, then a b + b c + c a = 0. On the other hand, if a = b = c = 1 3, then a b + b c + c a = 1. In fact, using ( a + b + c) 2 = a 2 + b 2 + c 2 + 2 ( a b + b c + c a), you get that a b + b c + c a = ( a + b + c) 2 − 1 2.
