Find the Maclaurin series for the function below and its radius of convergence. f(x) = 5 / sqrt(16 - x) SOLUTION We write f(x) in a form where we can use the binomial series. 5 √16 - x = 5 √ 16 Correct: Your answer is correct. (1 - x/16) = 5 4 Incorrect: Your answer is incorrect. = 5 4 (1 - x/16)-1/2 Using the binomial series with k =
