Harmonic numbers on the HP 50g
I recently discovered that the HP 50g function Psi (in MTH NXT SPECIAL) delivers the nth harmonic number:
Hn = Psi(n + 1) – Psi(1) [and that, by the way, –Psi(1) = 0.577215664902, the Euler constant]. This observation, together with the numerical SOLVE command, allows quick disposal of (say) the problem of finding the smallest integer k for which Hk > 7.6, and it might more generally be useful in mathematics teaching. |
