I have tried for a while to get it right...
I need to plot the three birythm curves. The curves start at your birthday, following a sinus waveform and have following periods: emotional curve 28 days, physical curve 23 days and intellectual 33 days.
I need to plot any ones curves for any interval, given the persons birthdate, startdate for the interval and length of the interval.
Anyone that can help on this one?
