Find the First Four Non-Zero Terms of the Taylor Series $f ( x ) = \cos 3 x + \sin 2 x$

True/False

Find the first four non-zero terms of the Taylor series at x = 0 of $f ( x ) = \cos 3 x + \sin 2 x$ .
Is $1 + 2 x - \frac { 9 x ^ { 2 } } { 2 ! } - \frac { 8 x ^ { 3 } } { 3 ! } + \ldots$ the correct answer?
