(d^2)/(dx^2)(sqrt(x^2+4))

\frac{d ^{2}}{d x ^{2}} (x^{2} + 4)

\frac{4}{( x ^{2} + 4 ) x ^{2} + 4}

Solution steps

\frac{d ^{2}}{d x ^{2}} (x^{2} + 4)

\frac{d}{d x} (x^{2} + 4) = \frac{x}{x ^{2} + 4}

= \frac{d}{d x} (\frac{x}{x ^{2} + 4})

\frac{d}{d x} (\frac{x}{x ^{2} + 4}) = \frac{4}{( x ^{2} + 4 ) x ^{2} + 4}

= \frac{4}{( x ^{2} + 4 ) x ^{2} + 4}

\frac{d y}{d x} = 4 x y

\frac{d}{d x} (\frac{x}{5 + x})

\int_{0}^{3} \frac{1}{3 x + 1} d x

\int \frac{1}{1 + 5 x ^{2}} d x

3 - 5 x
