\frac{d}{d x} (x y + ln (\frac{x}{y}))

y + x \frac{d y}{d x} + \frac{y - x \frac{d y}{d x}}{x y}

Solution steps

\frac{d}{d x} (x y + ln (\frac{x}{y}))

Apply the Sum/Difference Rule:

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

= \frac{d}{d x} (x y) + \frac{d}{d x} (ln (\frac{x}{y}))

\frac{d}{d x} (x y) = y + x \frac{d y}{d x}

\frac{d}{d x} (ln (\frac{x}{y})) = \frac{y - x \frac{d y}{d x}}{x y}

= y + x \frac{d y}{d x} + \frac{y - x \frac{d y}{d x}}{x y}

y^{^{''}} - 6 y^{^{'}} + 9 y = 0, y (0) = 2, y^{^{'}} (0) = \frac{25}{3}

\int 2 y - 5 d y

x \to + 3 - lim (f (x))

\int x (x - 2) d x
