d/(dy)(y^3+kxy^4-2x)

Lösung

\frac{d}{d y} (y^{3} + k x y^{4} - 2 x)

4 k y^{3} x + 3 y^{2}

Schritte zur Lösung

\frac{d}{d y} (y^{3} + k x y^{4} - 2 x)

Behandle

k, x

als Konstante

Wende die Summen-/Differenzregel an:

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

= \frac{d}{d y} (y^{3}) + \frac{d}{d y} (k x y^{4}) - \frac{d}{d y} (2 x)

\frac{d}{d y} (y^{3}) = 3 y^{2}

\frac{d}{d y} (k x y^{4}) = 4 x k y^{3}

\frac{d}{d y} (2 x) = 0

= 3 y^{2} + 4 x k y^{3} - 0

Vereinfache

= 4 k y^{3} x + 3 y^{2}

\int \frac{1}{x ^{2}} sin (\frac{1}{x}) cos (\frac{1}{x}) d x

\int_{0}^{2} 4 x^{2} - 2 x^{3} d x

\frac{d}{d x} (x (x - 3)^{2})

a re a y = x^{2}, y = - x^{2} + 4 x
