(\partial)/(\partial y)(x-2y)

\frac{\partial}{\partial y} (x - 2 y)

- 2

Solution steps

\frac{\partial}{\partial y} (x - 2 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} (2 y)

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

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

= 0 - 2

Simplify

= - 2

y^{^{''}} - 14 y^{^{'}} + 50 y = 0, y (0) = 10, y (\frac{π}{2}) = 3

f (x) = \frac{e ^{x} x - e ^{x}}{x ^{2}}

\frac{d}{d x} (e^{4 x - x^{2}})

\int x^{4} (1 - x^{2}) d x

f (x) = \frac{1}{( 1 + x )} 1
