I'm having real trouble proving the following
Every avenue I take reaches a dead end!
Thank you all very much in advance,
I think you should assume that |x| < 1 (otherwise the first term of the series will not be defined, being the log of a negative number).
Now use the power series expansion for –log(1–t) (valid when 0<t<1):
Substitute to see that and use the comparison test with .
what do I do/say in my argument to fix this?
Thanks in advance,
