Sure, it's the same formula. ;) (08272017 05:12 PM)Gerson W. Barbosa Wrote: Is there another calculator that offers this as a builtin function? I don't know one. But I admit I never understood why this rather special function has been implemented on the 34s and even got direct keyboard access. OK, there are a few occasions when the parallel function may be used for other mathematical applications, but IMvHO others would have made more sense. For instance functions that accurately evaluate √(1+x²) – 1, or in addition to e^{x}–1 a general a^{x}–1 function. Or 1–sin(x) and 1–cos(x). Or √(x²+y²). And let's not forget the useful DIVMOD function that simultaneously returns both quotient and remainder. Some of these are part of the Boost math package, so they seem to make sense for others, too. ;) On the other hand the  function can be programmed easily in just four steps, cf. the examples above.
