WebThe thing is you subtract ENDING POINT - STARTING POINT. The problem you're given will define the direction of the vector. So, if the direction defined by the problem is "A to B", you subtract Point B - Point A. If the direction is defined by the problem as "B to A", you subtract Point A - Point B.

WebThe scalar product is commutative: a ·b = b ·a. One can show that a · b is related to the components of a and b by: a·b = axbx +ayby +azbz (1.8) If two vectors are perpendicular then their scalar product is zero. The vector product (or cross product) of vectors a and b is a vector c whose mag-nitude is given by c = absinφ (1.9) WebMostly atoms with atomic number less than than 36 (Krypton), except for most of the transition metals.
