Can anyone please help me???
It asks to find the power series representation and radius of convergence for
f(x) = ln(a - x) for a>0
As an answer I got the series 1 to infinity of
__x^n___
a^n+1
I don't know if it is right and the radius of convergence I got was a but I don't know if that is right
f(x) = __x^3___
(1-4x)^2
I have no idea how to do this one...
Please help me
