Re: Series

Me too!


In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

Re: Series

Haha...Could it be done by differentiation?

Re: Series

Of what value is that to you? Are you not sure of your answer? These exercises are for each person to do by themselves.

Re: Series

Yes,the exercises are for individuals,but they must be checked for errors,otherwise,what's the point?
