# Thread: Bioryhtms equation

1. ## Bioryhtms equation

Physical potential Period 23 days
Emotional potential period 28 days
Intellectual potential period 33 days

If the equation determining each of your "potentials" is of the form

P(t)= 50 sin (at) + 50 where t is days and a is a constant specific to each of your potentials and P(t) is your potential after t days expressed as a percentage

How to find the value of a for each potential

And how to determine when the three "potentials" are each at their peak of 100%

when t=0 all potentials start at 50%

Any help always appreciated

To find a: Call the period of the cycle T. Then we know that one cycle corresponds to a time T. Thus
$\displaystyle 2 \pi = a T$

$\displaystyle a = \frac{2 \pi}{T}$

Each potential is at its peak when $\displaystyle sin(at) = 1$. So when
$\displaystyle at = \frac{\pi}{2}$

$\displaystyle t = \frac{\pi}{2a}$
or, if you insert the value of a from the first part:
$\displaystyle t = \frac{\pi}{2 \frac{2 \pi}{T}} = \frac{T}{4}$

3. ## Extension to the question...

Thank you. Muchly appreciated (again)

What then would be the easiest way of determining when all three cycles reach their peak simultaneously?
