(d^2)/(dx^2)(sqrt(x^2+9))

Lösung

\frac{d ^{2}}{d x ^{2}} (x^{2} + 9)

Lösung

\frac{9}{( x ^{2} + 9 ) x ^{2} + 9}

Schritte zur Lösung

\frac{d ^{2}}{d x ^{2}} (x^{2} + 9)

\frac{d}{d x} (x^{2} + 9) = \frac{x}{x ^{2} + 9}

= \frac{d}{d x} (\frac{x}{x ^{2} + 9})

\frac{d}{d x} (\frac{x}{x ^{2} + 9}) = \frac{9}{( x ^{2} + 9 ) x ^{2} + 9}

= \frac{9}{( x ^{2} + 9 ) x ^{2} + 9}
