Given that is a powers series representation for , find a power representaion for
I can't find out how to do these.
all help appreciated.
Knowing the sum of an infinite convergent geometric series to be where a is the first term and r is the common ratio, compare this to what they have given you.
For a is equal to x^3 and r is equal to -x^2. The first term will be x^3 and then multiply by -x^2 to generate the rest of the terms.
The power series representation of will be provided that for the first term n=0
Nevermind, looks like chisigma beat me to it.
