derivative y=sin(9x)+cos(7x)

Lösung

ableitung von

y = sin (9 x) + cos (7 x)

Lösung

cos (9 x) \cdot 9 - sin (7 x) \cdot 7

Schritte zur Lösung

\frac{d}{d x} (sin (9 x) + cos (7 x))

Wende die Summen-/Differenzregel an:

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

= \frac{d}{d x} (sin (9 x)) + \frac{d}{d x} (cos (7 x))

\frac{d}{d x} (sin (9 x)) = cos (9 x) \cdot 9

\frac{d}{d x} (cos (7 x)) = - sin (7 x) \cdot 7

= cos (9 x) \cdot 9 - sin (7 x) \cdot 7
