derivative of

\frac{2}{t + 1}

- \frac{2}{( t + 1 ) ^{2}}

Solution steps

\frac{d}{d t} (\frac{2}{t + 1})

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= 2 \frac{d}{d t} (\frac{1}{t + 1})

Apply exponent rule:

\frac{1}{a} = a^{- 1}

= 2 \frac{d}{d t} ((t + 1)^{- 1})

Apply the chain rule:

- \frac{1}{( t + 1 ) ^{2}} \frac{d}{d t} (t + 1)

= - \frac{1}{( t + 1 ) ^{2}} \frac{d}{d t} (t + 1)

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

= 2 (- \frac{1}{( t + 1 ) ^{2}} \cdot 1)

Simplify

2 (- \frac{1}{( t + 1 ) ^{2}} \cdot 1) : - \frac{2}{( t + 1 ) ^{2}}

= - \frac{2}{( t + 1 ) ^{2}}
