\frac{d}{d t} ((x) (t cos (t)))

\frac{d x}{d t} t cos (t) + (cos (t) - t sin (t)) x

Solution steps

\frac{d}{d t} ((x) (t cos (t)))

Apply the Product Rule:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = x, g = t cos (t)

= \frac{d x}{d t} t cos (t) + \frac{d}{d t} (t cos (t)) x

\frac{d}{d t} (t cos (t)) = cos (t) - t sin (t)

= \frac{d x}{d t} t cos (t) + (cos (t) - t sin (t)) x
