Have anyone ever coded a routine for drawing bio rythms? What is the formula? Kind regards Jon Lennart Aasenden Back to top Jon Lennart Aasenden Guest Posted: Thu Sep 02, 2004 7:30 am    Post subject: Re: Painting & calculating bio-rythms? Delphi7 has a dayssince/between() function in it's dateuttils unit, can i use that? Also, from the small programs i have seen, they renders 3 curves, how would the formula differ for the 3 states? For example, if i wanted to calculate the emotional state within the bounds of the last 14 days? Wish i did not suck so much as math.. im good at visual logic though :) Regards Jon Lennart Aasenden "Nils Haeck" <n.haeckno (AT) spamchello (DOT) nl> wrote Quote: It is something like cos(Days_Since_Birth / 23 * 2 * pi) - at least that's what I remember, cycles of 23 days. The trick is that you must calculate the number of days since birth *exactly* (so including leap years etc). You can do all that grunt work for that yourself, or use Delphi function EncodeDate twice (once for the time now, once for the birth date), then substract the two to get the number of days passed.

Hello Jon (From my old TI-58 manual, which included a program on biorythms) There seem to be three cycles, an physical cycle with a return period of 23 days, an emotional cycle with a return period of 28 days and a intellectual one with 33 days. In the formula cos(Days_Since_Birth / 23 * 2 * pi), the 23 is the magic number for the physical cycle. Further then this, I don't know nothing about biorythms Hope this helps Willem van Deursen Jon Lennart Aasenden wrote: Quote: Delphi7 has a dayssince/between() function in it's dateuttils unit, can i use that?

The trick is that you must calculate the number of days since birth *exactly* (so including leap years etc). Or just pick some random phase and frequency. I don't know what supposedly is the significance of "bio-rythms" but if it's somethin involving the number of days since birth, one would do just as well with any random function, it would seem to me.

You should use complex numbers. Specifically, the imaginary part comes in quite handy.

Concidering the odd's for someone like Bush becomming president, i would say the chances for god's existance is remarkably good :) Bio rythms on the other hand.. just a nice curiosity for my desktop toolbar. Also thinking about implementing tarot, runes and egyptian hekath, but well see. Thanks for all the help guys!
