(\partial)/(\partial x)(2/((x-3t)^2+1))

Lösung

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

Lösung

- \frac{4 ( x - 3 t )}{( ( x - 3 t ) ^{2} + 1 ) ^{2}}

Schritte zur Lösung

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

Behandle

t

als Konstante

Entferne die Konstante:

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

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

Wende Exponentenregel an:

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

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

Wende die Kettenregel an:

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

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

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

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

Vereinfache

2 - \frac{1}{( ( x - 3 t ) ^{2} + 1 ) ^{2}} \cdot 2 (x - 3 t) : - \frac{4 ( x - 3 t )}{( ( x - 3 t ) ^{2} + 1 ) ^{2}}

= - \frac{4 ( x - 3 t )}{( ( x - 3 t ) ^{2} + 1 ) ^{2}}
