Selecting variables

  1. Sep 22, 2015 #1

    I'm in the process of simplifying an equation at the moment. The question I have is: How do you select the variables when building an equation? For instance if I'm trying to explain "fastest observed velocity of matter" which letter or symbol do I use? Is there a list somewhere I'm not able to find listing these or do I make them up and publish a legend?

    this is a newbie question because I'm not formally schooled on this.

    There are no hard and fast rules. The speed of light (speed limit for everything) is "c".
