I just received the new Canon F-766S Scientific calculator and was shocked!

This little thing (US$ 15) is faster than anything I know. The simple 69! calculates instantly.

Mike Sebastian's calculator forensics (inv sin(inv cos(inv tan(tan(cos(sin 9)))))) takes less than 1 second and reports an amazingly precise 14 digits result of 8.9999999817692.

Yes, we know this result! The TI-89 uses the same 14 digits of "precision" and reports the same numbers.

How is this possibly? TI algorithm in Canon calculators? Shareware? Both calcs developed by Inventec?

Please advise...
