I am trying to expand some expansion in series before extracting a given coefficient. However, I face the following problem :


In[1440]:= Clear[x, c, y]

In[1441]:= Coefficient[(c + O[y]^2)*x, x]

Out[1441]= c

In[1442]:= Coefficient[(c*x) + O[x]^2, x]

Out[1442]= c

In[1443]:= Coefficient[(c + O[y]^2)*x + O[x]^2, x]

Out[1443]= 0




Does someone have a clue where this comes from ?



Thanks a lot in advance !
Best regards,
Victor
