Multiple Choice

Find the Maclaurin series for the function $$f ( x ) = \sin 7 x$$

A) $$\sin 7 x = \sum _ { n = 0 } ^ { \infty } \frac { ( - 1 ) ^ { n } ( 7 x ) ^ { 2 n + 1 } } { ( 2 n + 1 ) ! }$$
B)
$$\sin 7 x = \sum _ { n = 0 } ^ { \infty } \frac { ( - 1 ) ^ { n } ( 7 x ) ^ { 2 n } } { ( 2 n ) ! }$$
C)
$$\sin 7 x = \sum _ { n = 0 } ^ { \infty } \frac { ( 7 x ) ^ { 2 n } } { ( 2 n ) ! }$$
D)
$$\sin 7 x = \sum _ { n = 0 } ^ { \infty } \frac { ( - 1 ) ^ { n } ( 7 x ) ^ { 2 n + 1 } } { ( n + 1 ) ! }$$
E)
$$\sin 7 x = \sum _ { n = 0 } ^ { \infty } \frac { ( 7 x ) ^ { 2 n + 1 } } { ( 2 n + 1 ) ! }$$
