(\partial)/(\partial x)(-xe^{-xy})

\frac{\partial}{\partial x} (- x e^{- x y})

- e^{- x y} + e^{- x y} x y

Solution steps

\frac{\partial}{\partial x} (- x e^{- x y})

Treat

y

as a constant

Take the constant out:

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

= - \frac{\partial}{\partial x} (x e^{- x y})

Apply the Product Rule:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = x, g = e^{- x y}

= - (\frac{\partial}{\partial x} (x) e^{- x y} + \frac{\partial}{\partial x} (e^{- x y}) x)

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

\frac{\partial}{\partial x} (e^{- x y}) = - y e^{- y x}

= - (1 \cdot e^{- x y} + (- y e^{- y x}) x)

Simplify

= - e^{- x y} + e^{- x y} x y

\int \frac{31 x ^{2}}{x ^{2} - 4} d x

- 1

\frac{\partial}{\partial y} (x e^{x} sin (y))

(3 x^{4} - 12)^{\frac{1}{2}}

2 x^{2} + 7 x + 4
