Says No To Trig and Log Functions

I used a trigonomic function to get US Hwy-95 and NV Hwy-140 signs to evaluate to phi (the golden ratio).

   Hello RSM...

   It looks like you might not have any signs from Nevada.

   tan(140 - 95) = 1.61978

   Approximates 'phi' if truncated to the hundredths.

   The highway signs were found heading north on US Hwy-95
   about 30 miles from Winnemucca, Nevada.

On 19 April 2006 I was informed via an email message from that they were no longer allowing the use of trigonomic functions and log functions. In addition, they tightened the rules for signs evaluating to math constants such as pi, e, phi.

I agreed with's rule change and sent the following reply.

   Excellent rule change.  I was going to suggest that the constants
   be truncated to at least the thousandths.  Keep up the great work.

It is relatively easy to match mathematical constants to the hundredths and it appears as though agrees.

   That is an interesting idea. I'm going to see what happens to constant
   submissions now that we've removed these functions. If there are still
   too many, I may indeed act on your idea.

The following BARS were created over the span of three days and they demonstrate what is trying to eliminate via their rule change.

The highways signs from Illinois were accepted by prior to the rule change. The highways signs from Nevada were rejected because of the rule change. The highway signs from Utah and New Mexico were never submitted. Announce: Trigonometry Ruled Out, Constants Refined

Update::21 April 2006

I fooishly submitted IL Hwy-84 and US Hwy-20 signs to in order to receive two bonus points for submitting the first sign from Illinois.

   This is a huge stretch and I will understand
   completely if the sign is rejected.

   log(sqrt(84 x 20)) = 1.61265

   1.61265 truncated to the hundredths is 1.61

   The signs are located in the northwest corner
   of Illinois at the junction of IL Hwy-84 and
   US Hwy-20.

The signs were accepted and posted to RSM on 15 April 2006. Illinois Golden Ratio
