(\partial)/(\partial z)(xsin(y-z))

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

- x cos (y - z)

Solution steps

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

Treat

x, y

as constants

Take the constant out:

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

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

Apply the chain rule:

cos (y - z) \frac{\partial}{\partial z} (y - z)

= cos (y - z) \frac{\partial}{\partial z} (y - z)

\frac{\partial}{\partial z} (y - z) = - 1

= x cos (y - z) (- 1)

Simplify

= - x cos (y - z)

x \to 0 lim (5 e)

\frac{d}{d x} (\frac{9}{x + 7})

\frac{\partial}{\partial x} (sin (α) cos (β))

\frac{d}{d x} (24 e^{- 3 x})

\frac{d}{d t} (e^{6 t s i n (2 t)})
