arcsin(arccos(arctan(tan(cos(sin(9))))))





On the Calculator Forensics page,
[ http://www.rskey.org/~mwsebastian/miscprj/forensics.htm ]
the following formula is used to test calculators:

arcsin(arccos(arctan(tan(cos(sin(9))))))

Alas, some calculators (including the one that you get when
you copy the above equation into Google) only calculate trig
functions in radians.
See [ http://www.rskey.org/~mwsebastian/miscprj/radians.htm ]

Does anyone have a better method for running the Calculator
Forensics test on a radians-only calculator?
