Use the binomial series to expand the function as a power series. State the radius of convergence, R. Use a Maclaurin series in this table to obtain the Maclaurin series for the given function. f(x) = arctan(x6) n = 0Use a Maclaurin series in this table to obtain the Maclaurin series for the given function. f(x) = x cos(3x) CO n = 0Use a Maclaurin series in this table to obtain the Maclaurin series for the given function. f(x) = 9 sin2(x) [Hint Use sin2(x) = %(1 c05(2X))] ES)
