(\partial)/(\partial y)(cos(xyz))

Lösung

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

- sin (x yz) x z

Schritte zur Lösung

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

Behandle

x, z

als Konstanten

Wende die Kettenregel an:

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

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

\frac{\partial}{\partial y} (x yz) = x z

= - sin (x yz) x z
