Quiz 3：馬克勞林級數
\(\sin x\) 之馬克勞林級數展開為
\(\sum\limits_{n = 0}^\infty {{{( - 1)}^{^n}}\frac{{{x^{2n + 1}}}}{{(2n + 1)!}}} \)
\(\sum\limits_{n = 0}^\infty {\frac{{{x^n}}}{{n!}}} \)
\(\sum\limits_{n = 1}^\infty {\frac{{{x^n}}}{n}} \)
\(\sum\limits_{n = 0}^\infty {{{( - 1)}^{^n}}\frac{{{x^{2n + 1}}}}{{2n + 1}}} \)
