(\partial)/(\partial x)(5+e^{-xy}cos(y))

Lösung

\frac{\partial}{\partial x} (5 + e^{- x y} cos (y))

- e^{- x y} y cos (y)

Schritte zur Lösung

\frac{\partial}{\partial x} (5 + e^{- x y} cos (y))

Behandle

y

als Konstante

Wende die Summen-/Differenzregel an:

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

= \frac{\partial}{\partial x} (5) + \frac{\partial}{\partial x} (e^{- x y} cos (y))

\frac{\partial}{\partial x} (5) = 0

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

= 0 - y e^{- y x} cos (y)

Vereinfache

= - e^{- x y} y cos (y)
