(\partial)/(\partial y)(sqrt(y^2-9))

Lösung

\frac{\partial}{\partial y} (y^{2} - 9)

\frac{y}{y ^{2} - 9}

Schritte zur Lösung

\frac{\partial}{\partial y} (y^{2} - 9)

Wende die Kettenregel an:

\frac{1}{2 y ^{2} - 9} \frac{\partial}{\partial y} (y^{2} - 9)

= \frac{1}{2 y ^{2} - 9} \frac{\partial}{\partial y} (y^{2} - 9)

\frac{\partial}{\partial y} (y^{2} - 9) = 2 y

= \frac{1}{2 y ^{2} - 9} \cdot 2 y

Vereinfache

\frac{1}{2 y ^{2} - 9} \cdot 2 y : \frac{y}{y ^{2} - 9}

= \frac{y}{y ^{2} - 9}

\frac{d y}{d x} = - \frac{4 x + 4 y}{4 x + 9 y}

x \to 2 + lim (\frac{x - 3}{x ^{2} - 4})

\frac{\partial}{\partial y} (x^{4} + 8 x y^{7})
