derivative of-4cos^2(x)

Lösung

\frac{d}{d x} (- 4 cos^{2} (x))

4 sin (2 x)

Schritte zur Lösung

\frac{d}{d x} (- 4 cos^{2} (x))

Entferne die Konstante:

(a \cdot f)^{'} = a \cdot f^{'}

= - 4 \frac{d}{d x} (cos^{2} (x))

Wende die Kettenregel an:

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

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

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

= - 4 \cdot 2 cos (x) (- sin (x))

Vereinfache

- 4 \cdot 2 cos (x) (- sin (x)) : 4 sin (2 x)

= 4 sin (2 x)

n = 1 \sum \infty \frac{e}{π}

\int_{0}^{5} \frac{x - 3}{x ^{2} - 5 x - 6} d x

\frac{\partial}{\partial x} (sin (x) ln (x^{4} + \frac{1}{x}))

e^{y} + y cos (x) + (x e^{y} + sin (x)) \frac{d y}{d x} = 0

\int 4 x^{3} - 3 x^{2} + 6 x - 1 d x
