Homework Statement
The following series are not power series, but you can transform each one into a power
series by a change of variable and so find out where it converges.
∑∞0 ((3n(n+1)) / (x+1)n
Homework Equations
a power series is a series of the form:
a0 + a1x + a2x^2 ... + ...
The Attempt at a Solution
What exactly does it mean by transforming a power series by changing a variable? the only thing I could look up and find was converting to another coordinate plane in calculus 3 which would be further along than this problem focuses on... but i am still confused as i can't see how a series can be in a separate plane like that
