derivative of (sech(5x)^2)

Lösung

\frac{d}{d x} ((sech (5 x))^{2})

Lösung

- 10 sech^{2} (5 x) tanh (5 x)

Schritte zur Lösung

\frac{d}{d x} ((sech (5 x))^{2})

Wende die Kettenregel an:

2 sech (5 x) \frac{d}{d x} (sech (5 x))

= 2 sech (5 x) \frac{d}{d x} (sech (5 x))

\frac{d}{d x} (sech (5 x)) = - sech (5 x) tanh (5 x) \cdot 5

= 2 sech (5 x) (- sech (5 x) tanh (5 x) \cdot 5)

Vereinfache

2 sech (5 x) (- sech (5 x) tanh (5 x) \cdot 5) : - 10 sech^{2} (5 x) tanh (5 x)

= - 10 sech^{2} (5 x) tanh (5 x)
