Use the power series [ frac{1}{1+x}=sum_{n=0}^{infty}(-1)^{n} x^{n}, quad|x|<1 ] to find a power series for the function, centered at 0 . [ egin{array}{r} f(x)=ln (x+1)=int frac{1}{x+1} d x \ f(x)=sum_{n=0}^{infty}(square) end{array} ] Determine the interval of convergence. (Enter your answer using interval notation.) ( square )
