ignore this, wrong board
im trying to delete it
>>75127278
Why is the joker there instead of the riddler?
>>75127278
They all equal zero, the fourier cosine series is 0
>>75127582
correct

pls delete my post mods, it wont let me do it

If you can't answer this, you are the reason China is beating us. Give yourself a pat on the back, failure.

a0 can be any real number
all ak can be any real number
all bk must be zero

incorrect

oh, fuck odd. Misread that. Yeah, flippy floppy ak and bk.
>>75127278
Cosine is even so an coefficient ak must be zero. Or is this a trick and there is something more?
>>75128059
correct

Shouldn't a0 be 0 as well? Fourier expansions of odd functions only have sin terms.
