Entferne die Konstante:

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

= 2 \frac{\partial}{\partial t} (\frac{1}{( x - 3 t ) ^{2} + 1})

Wende Exponentenregel an:

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

= 2 \frac{\partial}{\partial t} (((x - 3 t)^{2} + 1)^{- 1})

Wende die Kettenregel an:

- \frac{1}{( ( x - 3 t ) ^{2} + 1 ) ^{2}} \frac{\partial}{\partial t} ((x - 3 t)^{2} + 1)

= - \frac{1}{( ( x - 3 t ) ^{2} + 1 ) ^{2}} \frac{\partial}{\partial t} ((x - 3 t)^{2} + 1)

\frac{\partial}{\partial t} ((x - 3 t)^{2} + 1) = - 6 (- 3 t + x)

= 2 - \frac{1}{( ( x - 3 t ) ^{2} + 1 ) ^{2}} (- 6 (- 3 t + x))
