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

Lösung

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

Lösung

- sin (2 x) \cdot 2

Schritte zur Lösung

\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

= - sin (2 x) \cdot 2
