(\partial)/(\partial y)(3ln(x)+ln(y))

Lösung

\frac{\partial}{\partial y} (3 ln (x) + ln (y))

\frac{1}{y}

Schritte zur Lösung

\frac{\partial}{\partial y} (3 ln (x) + ln (y))

Vereinfache

3 ln (x) + ln (y) : ln (x^{3} y)

= \frac{\partial}{\partial y} (ln (x^{3} y))

Behandle

x

als Konstante

Wende die Kettenregel an:

\frac{1}{x ^{3} y} \frac{\partial}{\partial y} (x^{3} y)

= \frac{1}{x ^{3} y} \frac{\partial}{\partial y} (x^{3} y)

\frac{\partial}{\partial y} (x^{3} y) = x^{3}

= \frac{1}{x ^{3} y} x^{3}

Vereinfache

\frac{1}{x ^{3} y} x^{3} : \frac{1}{y}

= \frac{1}{y}

y^{^{''}} + 16 y^{^{'}} = 0, y (0) = 2, y (0) = - 2
