derivative of cos(sqrt(x)-7x^2)

Lösung

\frac{d}{d x} (cos (x - 7 x^{2}))

- sin (x - 7 x^{2}) (\frac{1}{2 x} - 14 x)

Schritte zur Lösung

\frac{d}{d x} (cos (x - 7 x^{2}))

Wende die Kettenregel an:

- sin (x - 7 x^{2}) \frac{d}{d x} (x - 7 x^{2})

= - sin (x - 7 x^{2}) \frac{d}{d x} (x - 7 x^{2})

\frac{d}{d x} (x - 7 x^{2}) = \frac{1}{2 x} - 14 x

= - sin (x - 7 x^{2}) (\frac{1}{2 x} - 14 x)

\int \frac{2 x}{x ^{3} + 1} d x

\int \frac{tan ( x )}{cos ( x )} d x

\frac{\partial}{\partial y} (2 x y^{2})

\int_{0}^{8 π} x^{2} sin (2 x) d x
