Consider the power series (ac + 2)" . Specify the radius of convergence and centre of the power series, Determine the behaviour at the boundary points (if they exist). The radius of convergence is R = | The power series is centred at a = Describe the behaviour at the boundary points a - R and a + R, in that order, separated by a comma, Write a vector with 1 for absolutely convergent, 2 for conditionally convergent, 3 for divergent, 0 for not applicable (ie R is 0 or oo). (For instance, if the series were absolutely convergent at a - R and conditionally convergent at a + R you should input the vector [1, 2])
