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

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

\frac{2 x ^{2} - y}{x ( 2 x ^{2} + y )}

Solution steps

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

Treat

y

as a constant

Apply the chain rule:

\frac{1}{x + \frac{y}{2 x}} \frac{\partial}{\partial x} (x + \frac{y}{2 x})

= \frac{1}{x + \frac{y}{2 x}} \frac{\partial}{\partial x} (x + \frac{y}{2 x})

\frac{\partial}{\partial x} (x + \frac{y}{2 x}) = 1 - \frac{y}{2 x ^{2}}

= \frac{1}{x + \frac{y}{2 x}} (1 - \frac{y}{2 x ^{2}})

Simplify

\frac{1}{x + \frac{y}{2 x}} (1 - \frac{y}{2 x ^{2}}) : \frac{2 x ^{2} - y}{x ( 2 x ^{2} + y )}

= \frac{2 x ^{2} - y}{x ( 2 x ^{2} + y )}

x \to \infty lim ((1 + \frac{7}{x})^{2 x})

\frac{d}{d x} (x^{2} + \frac{2 a ^{3}}{x})

x \to + 3 - lim (\frac{3}{x ^{2} - 9})

y^{3} - (14 x + 8) + 3 x y^{2} y^{^{'}} = 0

x^{^{'}} = x
