Since each atan takes as its function tan, since each acos takes as its function cos, since each asin takes as its function sin; may I suggest some elimination of terms. This yields
9°=9°
9°=9°
9°=9°
9°=9°
9°=9°
Which demonstrates ideal accuracy ;)

Hello!
Finally I managed to grab a CASIO fx-98. Very happy now! :) Perfectly fits into a wallet, now all I need carry along is a long-term Sun/stars table and a cheat-list with few formulas. (and a watch!)
However, these are limitations:
CASIO fx-98:
- atan(acos(asin(sin(cos(tan(9°))))))=8,9999564°
- acos(atan(asin(sin(tan(cos(9°))))))=9°
- asin(acos(atan(tan(cos(sin(9°))))))=9,0000157°
- acos(asin(atan(tan(sin(cos(9°))))))=9°
- asin(atan(acos(cos(tan(sin(9°))))))=8,4421811°
- atan(asin(acos(cos(sin(tan(9°))))))=8,7535133°
Yes, it is sort of artificial and unrealistic calculation but one must be alert.
Warm regards,
