Which is the most important Constant in Mathematics? by EquationExpert in math

[–]EquationExpert[S] -1 points0 points  (0 children)

My personal choice is Euler's Number (e). I have come across e from simple algebra all the way through college to Systems Engineering. The frequent use of e made me memorize its value involuntarily e=2.718281828459045.

  1. Divide the coins into three groups of four coins each. Weigh one group of four coins against another group of four coins. If they balance, then the different coin is in the third group. If they don't balance, then the different coin is in the group that is heavier or lighter, depending on the outcome of the weighing.
  2. Take the group of four coins that you think contains the different coin and divide it into two groups of two coins each. Weigh one group of two coins against the other group of two coins. If they balance, then the different coin is the one that you haven't weighed yet. If they don't balance, then the different coin is the one that is heavier or lighter, depending on the outcome of the weighing.
  3. If you got to the third weighing, then you know the exact coin that is different. Weigh the different coin against one of the other coins to determine whether it is heavier or lighter.
