(a) find the Maclaurin polynomial \(\displaystyle{P}_{{{3}}}{\left({x}\right)}\) for f(x), (b) complete the following

\(\begin{array}{|c|c|}\hline x: & -0.75 & -0.50 & -0.25 & 0 & 0.25 & 0.50 & 0.75 \\ \hline \end{array}\)

for f(x) and \(P_{3}(x)\) and (c) sketch the graphs of f(x) and \(\displaystyle{P}_{{{3}}}{\left({x}\right)}\) on the same set of coordinate axes. \(\displaystyle{f{{\left({x}\right)}}}={\arctan{{x}}}\)
