Fourier Series Formula, Tutorial v.s. KA Stroud

[jameshume]

Hi All,

The formula for the fourier series in the tutorial swaps the a_i and b_i coeffecients w.r.t the sine and cosine components when compared to the formula I have read in K.A. stroud.

Tutorial:

SUM(A_n sin wt + B_n cos wt)


Stroud:

SUM(A_n cos wt + B_n sin wt)



This seems just like a basic variable rename, but I was just wondering (just in case), if this has any impact? Is one way more standard than the other for example?

Thanks for any help
James
