(\partial)/(\partial y)(x^2-2y^2)

Lösung

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

- 4 y

Schritte zur Lösung

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

Behandle

x

als Konstante

Wende die Summen-/Differenzregel an:

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

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

\frac{\partial}{\partial y} (x^{2}) = 0

\frac{\partial}{\partial y} (2 y^{2}) = 4 y

= 0 - 4 y

Vereinfache

= - 4 y

t an g e n t f (x) = (1 + 4 x) (5 - 2 x), at x = 2

\frac{\partial}{\partial y} (x^{2} + 3 y^{2})

t an g e n t f (x) = sin (sin (x)), 0, at x = π
