O Initial points together The dot product of two vectors is a scalar Example Compute v · w knowing that v w ? R3 with v = 2 w = h1 2 3i and the angle in between is ? = ?/4 Solution: We first compute w that is w2 = 12 + 22 + 32 = 14 ? ? w = 14 We now use the definition of dot product: ? ? 2 · w = v w cos(?) = (2) 14 2
