derivative (4x^2-5x)e^x

Lösung

ableitung von

(4 x^{2} - 5 x) e^{x}

4 e^{x} x^{2} + 3 e^{x} x - 5 e^{x}

Schritte zur Lösung

\frac{d}{d x} ((4 x^{2} - 5 x) e^{x})

Wende die Produktregel an:

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

f = 4 x^{2} - 5 x, g = e^{x}

= \frac{d}{d x} (4 x^{2} - 5 x) e^{x} + \frac{d}{d x} (e^{x}) (4 x^{2} - 5 x)

\frac{d}{d x} (4 x^{2} - 5 x) = 8 x - 5

\frac{d}{d x} (e^{x}) = e^{x}

= (8 x - 5) e^{x} + e^{x} (4 x^{2} - 5 x)

Vereinfache

(8 x - 5) e^{x} + e^{x} (4 x^{2} - 5 x) : 4 e^{x} x^{2} + 3 e^{x} x - 5 e^{x}

= 4 e^{x} x^{2} + 3 e^{x} x - 5 e^{x}

\frac{d}{d x} (\frac{sin ( \frac{π}{2} x )}{x})

\frac{d}{d x} (x x^{2} + y^{2})

\int_{0}^{\frac{1}{5}} 5 arcsin (5 y) d y

f (x) = cos (5 x)
