Biorhythms on the HP12C


Here, I'd like to present you the program I run on my HP12C.
Such a program to achieve on this calculator is rather easy because it has built-in functions for performing date calculations.

The only major problem to be resolved lies in the calculation of the sine from which the display of the biorhythm results : no trigonometric functions available on the HP12C !

Rather difficult to override for me...

Finally, I found a routine, made by Valentin Albillo on the HPCC site.
(See HP-12C Tried & Tricky Trigonometrics).

Thanks a lot, Valentin Albillo.
