Is there an easy way to change the worksheet radian default to degrees
so that I don´t have to use the 180/PI or PI/180 or the degrees
function.

The following is a formula to derive the Log Haversine of the number
30,

Log((1-Cos(30*PI()/180)))/2)+10

and the following is to derive the number 30 from the Log Haversine,

(Acos(1-(10^((D18-10))*2))*180/PI())/24 D18 being the cell
with the log haversine.

Surely there is an easier way to get a log haversine than this. Any
help will be most appreciated.
