>"Tau is 2 time pi or about 6.28 as pi is about 3.14. "   
      
   Wow, thanks. Now I see how I so misunderstood my math tutor. And the wire   
   thing, if I use radius instead of diameter then it is tau, why was that so   
   damn hard to pick up ?    
      
   My math tutor is very advanced and I find him nearly impossible to follow. I   
   am his electronics tutor and he probably finds me the same. Granted I am only   
   half there, but he is still in the basics and I can handle that. In math, he   
   goes too far too fast.    
   Maybe I am slow...   
      
   Thanks for the answer. I will think up more questions. Don't get floored by   
   them.
