I just tried :
=degrees(asin(acos(atan(tan(cos(sin(9*pi()/180))))))
on EXCEL2002 and got a very good result of 9.000000000000010
Well done Microsoft!

I got the same result of 9.000000000000010 on Excel 97.

BTW, Gordon omitted one close-paren. The formula should read:

=DEGREES(ASIN(ACOS(ATAN(TAN(COS(SIN(9*PI()/180)))))))
