derivative of cos(pi/2-3x)

Lösung

\frac{d}{d x} (cos (\frac{π}{2} - 3 x))

Lösung

cos (3 x) \cdot 3

Schritte zur Lösung

\frac{d}{d x} (cos (\frac{π}{2} - 3 x))

Vereinfache

cos (\frac{π}{2} - 3 x) : sin (3 x)

= \frac{d}{d x} (sin (3 x))

Wende die Kettenregel an:

cos (3 x) \frac{d}{d x} (3 x)

= cos (3 x) \frac{d}{d x} (3 x)

\frac{d}{d x} (3 x) = 3

= cos (3 x) \cdot 3
