[PD] cosinesum vs sinesum in arrays

[Peter P.]

Dear List,

not sure if I am getting something wrong here, but it seems that
sending the message 

; cosinesum array999 1

does something different (besides an obvious phase shift between sine
and cosine functions) to the resulting contents of that table:

the first partial on cosinesum seems to be the DC component, while the
first partial in sinesum is the, well, first partial. 

Accordingly, the second partials have double frequency in sinesum as
in cosinesum.

Perhaps this is intentional, but was just wondering...

best, Peter
