(Give your power series representation centered at x = 0.) f(x)= ln(1-8x).Because when they ask to find power series representation of $\ln(1-x)$ you have to first find derivative of this then convert it into series and then find antiderivative of this series.We will be representing many functions as power series and it will be important to recognize that the representations will often only be valid for a range of \(x This is an important idea to remember as it can often greatly simplify our work. Example 3 Find a power series representation for the following...Find a power representation for the function and determine the radius of convergence. f(x)=x^(2)arctan(x^(3)).Dr. Marcel B.

Start from the sum of the geometric series:

#sum_(n=0)^oo q^n = 1/(1-q)#

converging for #abs q < 1#.

Let # x = -q # to have:

#sum_(n=0)^oo (-1)^nx^n = 1/(1+x)#

Inside the interval of convergence #x in (-1,1)# we will be able to combine the series term by means of term:

#int_0^x dt/(1+t) = sum_(n=0)^oo int_0^x (-1)^nt^ndt#

and acquire a series with the similar radius of convergence #R=1#:

#ln(1+x) = sum_(n=0)^oo (-1)^nx^(n+1)/(n+1)#
