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

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

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

Solution steps

\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}

f (x) = - x^{2} - x + 3, at x = - 3

\int x^{2} 8 - x^{2} d x

\int cot^{2} (x) (1 + tan^{2} (x)) d x

6 t^{4}

f (x) = 4 - x^{2}, at x = - 1
