One way to use degrees in a spreadsheet is to convert them
to radians within the cosine or sine function. In Works,
pi() (this is pi with empty parenthesis) is pi, so use pi
radians per 180 degrees to convert. An example
spreadsheet follows. I hope the tab stops come through
OK.
A B C
1 deg formula answer
2 0 =cos(pi()/180*a2) 1
3 45 =cos(pi()/180*a3) 0.7071
4 90 =cos(pi()/180*a4) 0
5 135 =cos(pi()/180*a5) -0.7071
6 180 =cos(pi()/180*a6) -1
