I am trying to calculate Fourier Series coefficients(a1 & b1) using formulae in excel for a particular case.
In a book by Henry Ludwell Moore, 'Economic Cycles :Their Law & Cause', the author has calculated these coefficients for rainfall data in Ohio valley.
I am able to calculate them correctly for the cycles which divide the total data completely ( e.g. 8th cycle in 72 readings sample).
But I am unable to calculate for other cycles. (e.g. 10th cycle in 72 readings)
I am unable to attach my worksheet and Moore's calculations for your kind reference.
