Little White Sign IV

David Slauenwhite brings another "Little White Sign" to Road Sign Math. This one is from the far reaches of rural Pennsylvania and a little village called Covington. While the sign is little, the math certainly is not.



Slauenwhite introduces a new trigonometry function with this submission, secant, never before used in any sign.

$$2,022 + \sec (100 - 40) ^\circ + \sin 90^\circ = 2,025$$

This sign is at the intersection of Canada Road and West Hill Road in the sleepy little village of Covington, Pennsylvania.
