1. The problem statement, all variables and given/known data Let a and b denote two 2D vectors a = <a1, a2> b=<b1, b2> show directly that a . b ≤ ||a||||b|| 2. Relevant equations 3. The attempt at a solution Im looking for a place to start here. Should i start by computing the dot product of a and b and then also finding the magnitude of a and b?
