(\partial)/(\partial x)(cos(3x+4y))

Lösung

\frac{\partial}{\partial x} (cos (3 x + 4 y))

Lösung

- sin (3 x + 4 y) \cdot 3

Schritte zur Lösung

\frac{\partial}{\partial x} (cos (3 x + 4 y))

Behandle

y

als Konstante

Wende die Kettenregel an:

- sin (3 x + 4 y) \frac{\partial}{\partial x} (3 x + 4 y)

= - sin (3 x + 4 y) \frac{\partial}{\partial x} (3 x + 4 y)

\frac{\partial}{\partial x} (3 x + 4 y) = 3

= - sin (3 x + 4 y) \cdot 3
