(\partial)/(\partial y)(cos(2xy))

Lösung

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

- sin (2 x y) \cdot 2 x

Schritte zur Lösung

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

Behandle

x

als Konstante

Wende die Kettenregel an:

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

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

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

= - sin (2 x y) \cdot 2 x

\int_{- 1}^{1} \frac{5 x}{( x + 3 ) ^{2}} d x

\int \frac{1}{1 + 4 y ^{2}} d y
