Just a curious mathematical result
Hi all,

Just to let you know about a curious mathematical result I discovered recently. In radians:

      Sin(9*(Sin(1) + Cos(40))) =    0.999999999999999830826985368...

which differs from the integer 1 by about 1e16. If you compute it on a 12-digit machine (such as the HP-71B) y will probable get evaluated as exactly 1. The correct value requires more than 12 digits, in a pinch the Windows calculator will do.

¿ Nice, isn't it ?
