SUMMARY
The first derivative of the function x(t) = Acos(wt) + Bsin(wt) + (F/(2mw))tsin(wt) is correctly calculated as -Awsin(wt) + Bwcos(wt) + (Ftcos(wt) + Fsin(wt))/(2mw). The discussion highlights a critical observation regarding a missing factor of w in the first term of the numerator of the fraction, emphasizing the importance of accurate differentiation in trigonometric functions involving angular frequency.
