The Frontier State makes its introduction with mathematically significant roadsigns with this sign found by David Slauenwhite. In addition to being an interesting mathematical sign, notice that all the cities on the sign start with C. Alaska is no place to travel with a low tank of gas!

A sign with a city named Circle in it is so enticing to try to get 360 or another number that is relevant to a circle but it wasn't meant to be. However, the answer was still found in trigonometry.

$\tan ( 152 - 17 )^\circ = 117 - 118$

This sign is found at the very beginning of Highway 6 in Alaska leaving the city Fox.
