d/(dt)(cos^2(t))

Lösung

\frac{d}{d t} (cos^{2} (t))

Lösung

- sin (2 t)

Schritte zur Lösung

\frac{d}{d t} (cos^{2} (t))

Wende die Kettenregel an:

2 cos (t) \frac{d}{d t} (cos (t))

= 2 cos (t) \frac{d}{d t} (cos (t))

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

= 2 cos (t) (- sin (t))

Vereinfache

2 cos (t) (- sin (t)) : - sin (2 t)

= - sin (2 t)
