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

Lösung

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

- sin (x)

Schritte zur Lösung

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

Behandle

y

als Konstante

Wende die Summen-/Differenzregel an:

(f \pm g)^{'} = f^{'} \pm g^{'}

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

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

\frac{\partial}{\partial x} (cos (y)) = 0

\frac{\partial}{\partial x} (y) = 0

= - sin (x) + 0 - 0
