(\partial)/(\partial z)(x+2y+z)

\frac{\partial}{\partial z} (x + 2 y + z)

1

Solution steps

\frac{\partial}{\partial z} (x + 2 y + z)

Treat

x, y

as constants

Apply the Sum/Difference Rule:

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

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

\frac{\partial}{\partial z} (x) = 0

\frac{\partial}{\partial z} (2 y) = 0

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

= 0 + 0 + 1

Simplify

= 1

\int_{0}^{4} 1 + e^{- 2 y} d y

\int \frac{28 s + 28}{( s ^{2} + 1 ) ( s - 1 ) ^{3}} d s

\frac{\partial}{\partial x} (3 x + 4 y^{2} + 3 x^{2} y^{3})

\int_{1}^{3} u^{2} + b^{2} d u

\int x - 2 π d x
