Answer:
then BA = a ... Two vectors a and b are said to be equal if they have the same ... P P = –4i –9j + 5k. Example 2: Find the magnitude of the vector. 3 2. 2 3 u = i j + ... a 3i 2j + 4k. = - and b 2i + j + 3k. = find the magnitude and direction cosines of. (i ) ... b . a = | | Cosθ. = a b Cosθ b . a = a . b. Hence the dot product is commutative
