Question

Use the power series for the function, centered at 0, and deermine the interval of convergence:

f(x) = - 1/(x+1)^2  = d/dx[1/(x+1)]

Using a Power Series In Exercises 19, 20, 21, 22, 23, 24, 25, 26, 27, and 28, use the power series
1
E(-1)"x", |æ| <1
1+x
n=0
to find a power series for the function, centered at 0, and determine the interval of convergence.
