\frac{d}{d t} ((z (t)) (t))

t \frac{d}{d t} (z (t)) + z (t)

Solution steps

\frac{d}{d t} ((z (t)) (t))

Apply the Product Rule:

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

f = z (t), g = t

= \frac{d}{d t} (z (t)) t + \frac{d t}{d t} z (t)

\frac{d t}{d t} = 1

= \frac{d}{d t} (z (t)) t + 1 \cdot z (t)

Simplify

= t \frac{d}{d t} (z (t)) + z (t)

(4 m^{4} - 8 mn)^{2}

(x + 2)^{2} - 14 (x + 2) + 48

(x)^{2} + (y)^{2}

\frac{x - 1}{x ^{2} + x - 2}

4 - (a + 1)^{3}
