As far as I am concerned I would agree. The only time I have ever come across hyperbolic functions was in connection with differential equations. Back at university. But, as already discussed in an earlier thread, at university the numeric result of an excercise was of secondary interest. You would already get full points for writing something like y = e^−x/6(c1 cosh(x2) +c2 sinh(x2))

The Ti-59 I had back then would not have been able to compute hyperbolic functions unsless one either programmed them oneself (as I certainly did even if I don't remember now...) or bought the "Math Utilities" module.

NB and off topic, regarding Paul Dales reply: On of my super-hardened-iron-clad rules is to never ever let a dishwasher or washing machine run unattended when nobody is at home. I know many cases among family and friends where a malfuntioning washing machine has caused considerable damage by flooding the appartment. I certainly wouldn't want to drown my calculator collection in dirty dishwasher waste water... Therefore the first thing I would disable in such a machine is the remote operation!
