Initially the Daniel Equation may appear a bit obtuse, but those familiar with calculus and trigonometry will notice a few curious aspects:
- The first integral of the equation, which is made entirely of sines (with what amount to frequency terms coming only in even multiples), is integrated from 0 to 2 pi, and so obviously the area under the curve of this equation must thus sum to zero despite it being an infinite series.
- That this series relates to the stages of insight is obvious also.
- The outer integral is dt (d time), and there is no time term in the equation at all.
- Pondering those two facts may lead to illumination, perhaps.
