derivative of-sin(7x^2*14x)

Lösung

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

- 14 (14 x^{2} cos (7 x^{2}) + sin (7 x^{2}))

Schritte zur Lösung

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

Entferne die Konstante:

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

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

Wende die Produktregel an:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = sin (7 x^{2}), g = x

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

\frac{d}{d x} (sin (7 x^{2})) = cos (7 x^{2}) \cdot 14 x

\frac{d x}{d x} = 1

= - 14 (cos (7 x^{2}) \cdot 14 xx + 1 \cdot sin (7 x^{2}))

Vereinfache

- 14 (cos (7 x^{2}) \cdot 14 xx + 1 \cdot sin (7 x^{2})) : - 14 (14 x^{2} cos (7 x^{2}) + sin (7 x^{2}))

= - 14 (14 x^{2} cos (7 x^{2}) + sin (7 x^{2}))

\frac{d x}{d t} + 2 t x = t, x (0) = \frac{3}{2}

t an g e n t f (x) = 5 x^{3} + 4 x, at x = - 3

f (x) = x \cdot cos (x)
