(\partial)/(\partial y)(-x-y)

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

- 1

Solution steps

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

Treat

x

as a constant

Apply the Sum/Difference Rule:

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

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

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

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

= - 0 - 1

Simplify

= - 1

x \to - \infty lim (e^{3 x})

y^{^{'}} - \frac{7}{x} y = \frac{y ^{4}}{x ^{5}}

x y d y + e^{- x} (y^{2} - 1) d x = 0

y^{^{'}} = \frac{( y - x )}{( x )}

\frac{d y}{d x} = \frac{x ^{2}}{x ^{2} + 1}
