We need to fill in the Maclaurin (Taylor around 0) series coefficients for three functions and their first few terms. A) f(x) = 2 cos(x) - The Maclaurin series for cos(x) is 1 − x^2/2! + x^4/4! − …, i.e., cos(x) = 1 − x^2/2 + x^4/24 − … - Multiplying by 2 gives f(x) = 2 cos(x) = 2 − x^2 + (2/24) x^4 − … = 2 + 0·x + (−1)·x^2 + … - Therefore, the constant term is 2, the coefficient of x......Login to view full explanation
