It's an actual formatting bug in Series. WRI ought to fix it. In the meantime you have to think of it as +(-I q s). It goes away if you use Normal. Series[-I q s - I p Sqrt[K1^2 - s^2], {s, 0, 1}] % // Normal David Park djmp at earthlink.net http://home.earthlink.net/~djmp/ From: AES/newspost [mailto:siegman at stanford.edu] To: mathgroup at smc.vnet.net The input In[13]:= Series[-I q s - I p Sqrt[K1^2 - s^2], {s, 0, 1}] gives Out[13]= -I Sqrt[K1^2] p + - I q s + O[s^2] whereas In[14]:= Series[-I q s - I p Sqrt[K1^2 - s^2], {s, 0, 1}] // Normal gives Out[14]= -I Sqrt[K1^2] p - I q s What's that "+ -" doing in Out[13] ? Is this normal?
