I've been trying to get this for 2 hours now with not even a clue on how to start. The question is.... x,y,z are positive numbers... and 5x + y + 6z = 11, find the minimum value of 1/x + 6/y + 5/z. It gives a hint saying to use the Cauchy Schwarz inequality | U (dot) V | is less than or equal to ||U|| ||V||.
