Hi,

http://books.google.at/books?id=40rRzNbuhpAC&pg=PA146

Can anybody explain me why in the third bracket in 3.139 is suddenly a minus instead of a plus? In 3.136 it is a Plus! And it is pure substitution as far as I understand...

And I checked everything before a few times: It should be correct!

And the next crazy stuff: From where does suddenly the "i" in the numerator (3.140) appear?

Thank you :-)

Hi divB!

You're absolutely right. There is a plus sign in the 3rd bracket and some confusion with factors of i in (3.140).

I found a later version of his book, where the errors are corrected. I attached a bmp of the relevant page.

Enjoy the book!

Best regards Martin
