(\partial)/(\partial x)(cos(2x)*2)

Lösung

\frac{\partial}{\partial x} (cos (2 x) \cdot 2)

- 4 sin (2 x)

Schritte zur Lösung

\frac{\partial}{\partial x} (cos (2 x) \cdot 2)

Entferne die Konstante:

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

= 2 \frac{\partial}{\partial x} (cos (2 x))

Wende die Kettenregel an:

- sin (2 x) \frac{\partial}{\partial x} (2 x)

= - sin (2 x) \frac{\partial}{\partial x} (2 x)

\frac{\partial}{\partial x} (2 x) = 2

= 2 (- sin (2 x) \cdot 2)
