Expert Solution

A Maclaurin series is a Taylor series expansion of a function about 0. A Maclaurin series is used to approximate a function, verify the antiderivative of a complicated function, or compute an otherwise uncomputable sum. As we are familiar with the Maclaurin formula the series is calculated by taking derivatives of a given function at where, x = 0. The five-time derivatives for x=0 are calculated and their values are put in the formula and calculated in the series. Thus, the series is simplified and similarly calculated for the remaining two functions.
