derivative of cos(x-7x)

Lösung

\frac{d}{d x} (cos (x) - 7 x)

- sin (x) - 7

Schritte zur Lösung

\frac{d}{d x} (cos (x) - 7 x)

Wende die Summen-/Differenzregel an:

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

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

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

\frac{d}{d x} (7 x) = 7

= - sin (x) - 7

n = 0 \sum \infty - 2^{n}

\int_{0}^{1} x 1 + 8 x^{2} d x

\int (x^{2} - 4 x + 3) d x

\int sin^{4} (2 x) cos^{3} (2 x) d x

\frac{\partial}{\partial x} ((3 x + 4 y) e^{y})
