derivative of

\frac{1}{2 t - 1}

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

Solution steps

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

Apply exponent rule:

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

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

Apply the chain rule:

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

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

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

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

Simplify

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

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