Considering the function, find the solutions, show your works:

1 — cos(x4) Consider f(x) = x4 (51) Use a Maclaurin series from Table 1 in section 11.10 of the text to find the Maclaurin series of f(x). f(x) = i n=l (b) Find the interval of convergence for the series in (a). State the answer using interval notation. XE Note: Input U. infinity, and -infinity for union, co, and —oo, respectively.
