(\partial)/(\partial x)(cos(x+y))

Lösung

\frac{\partial}{\partial x} (cos (x + y))

Lösung

- sin (x + y)

Schritte zur Lösung

\frac{\partial}{\partial x} (cos (x + y))

Behandle

y

als Konstante

Wende die Kettenregel an:

- sin (x + y) \frac{\partial}{\partial x} (x + y)

= - sin (x + y) \frac{\partial}{\partial x} (x + y)

\frac{\partial}{\partial x} (x + y) = 1

= - sin (x + y) \cdot 1

Vereinfache

= - sin (x + y)
