(\partial)/(\partial x)(cos(x+8y))

Lösung

\frac{\partial}{\partial x} (cos (x + 8 y))

- sin (x + 8 y)

Schritte zur Lösung

\frac{\partial}{\partial x} (cos (x + 8 y))

Behandle

y

als Konstante

Wende die Kettenregel an:

- sin (x + 8 y) \frac{\partial}{\partial x} (x + 8 y)

= - sin (x + 8 y) \frac{\partial}{\partial x} (x + 8 y)

\frac{\partial}{\partial x} (x + 8 y) = 1

= - sin (x + 8 y) \cdot 1

Vereinfache

= - sin (x + 8 y)

\int_{0}^{l n (2)} \frac{e ^{3 x}}{1 + e ^{6 x}} d x

x \cdot \frac{d y}{d x} + 2 y = 3

\frac{d}{d x} (5 - ∣ x - 5 ∣)

\frac{\partial}{\partial o} (r cos (o))

\frac{\partial}{\partial x} (- 36 y sin (9 x))
