(\partial)/(\partial z)(-2e^xcos(yz))

\frac{\partial}{\partial z} (- 2 e^{x} cos (yz))

2 e^{x} y sin (yz)

Solution steps

\frac{\partial}{\partial z} (- 2 e^{x} cos (yz))

Treat

x, y

as constants

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= - 2 e^{x} \frac{\partial}{\partial z} (cos (yz))

Apply the chain rule:

- sin (yz) \frac{\partial}{\partial z} (yz)

= - sin (yz) \frac{\partial}{\partial z} (yz)

\frac{\partial}{\partial z} (yz) = y

= - 2 e^{x} (- sin (yz) y)

Simplify

= 2 e^{x} y sin (yz)

\int x^{3} (1 + x^{4})^{3} d x

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

\int_{- \infty}^{0} \frac{1}{4 - 3 x} d x

\frac{s}{( s - 3 ) ^{3}}

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