derivative of e^ycos(x)

Lösung

\frac{d}{d x} (e^{y} cos (x))

Lösung

e^{y} cos (x) \frac{d y}{d x} - e^{y} sin (x)

Schritte zur Lösung

\frac{d}{d x} (e^{y} cos (x))

Wende die Produktregel an:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = e^{y}, g = cos (x)

= \frac{d}{d x} (e^{y}) cos (x) + \frac{d}{d x} (cos (x)) e^{y}

\frac{d}{d x} (e^{y}) = e^{y} \frac{d y}{d x}

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

= e^{y} \frac{d y}{d x} cos (x) + (- sin (x)) e^{y}

Vereinfache

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