Residues
hi all,
calculating residue of \( sin(z)^{-1} \) in z=0 I get 1, ok. Calculating residue of \( sin(z^{-1}) \) in z=0 I get 0, but I think I should get 1, instead... (The Laurent series is 1/z-1/(6 z^3)+1/(120 z^5)-1/(5040 z^7)+1/(362880 z^9)-1/(39916800 z^11)+o((1/z)^13) ...) Am I wrong? Thank you Salvo EDIT: here (and in a book of mine) they say 1... ∫aL√0mic (IT9CLU) :: HP Prime 50g 41CX 71b 42s 39s 35s 12C 15C - DM42, DM41X - WP34s Prime Soft. Lib |
