Answer the following:

Base your answers on the equation below: ftr) = 44\": _$2' A. Use the geometric: series to find a power series representation for f(x) about 0 and give its interval of convergence. B. After differentiating the power series obtained from A, find a power series representation for ( ) 4 + 332 a: : 9 (4 $2)?\" _ _ 00 2n + 1 then use an approprlate value of x to detelrmlne the sum of 4n+1 . n20
