ok, I'll try to copy/paste as soon as possible later, however I tried to do like you did. The issue was after the message "warning"...
Later I'll try again.

For now I'm trying also with a program like this:

Code:


#cas
fourcoeff(fun,k)
BEGIN
local a0:=(int(fun,t,0,2*PI))/(2*PI);
local ak:=(int(fun*cos(k*t),t,0,2*PI))/PI;
local bk:=(int(fun*sin(k*t),t,0,2*PI))/PI;
return a0,ak,bk;
END;
#end

it should give a0 (the first), ak and bk coefficient for k and a function.
It could be made better; if I miss the local command for variables it give formulas with something like 256 or 1024 added, I don't understand why...

Thank you for your effort!
