(d^2)/(dx^2)((1-4x)/(1+4x))

\frac{d ^{2}}{d x ^{2}} (\frac{1 - 4 x}{1 + 4 x})

\frac{64}{( 1 + 4 x ) ^{3}}

Solution steps

\frac{d ^{2}}{d x ^{2}} (\frac{1 - 4 x}{1 + 4 x})

\frac{d}{d x} (\frac{1 - 4 x}{1 + 4 x}) = - \frac{8}{( 1 + 4 x ) ^{2}}

= \frac{d}{d x} (- \frac{8}{( 1 + 4 x ) ^{2}})

\frac{d}{d x} (- \frac{8}{( 1 + 4 x ) ^{2}}) = \frac{64}{( 1 + 4 x ) ^{3}}

= \frac{64}{( 1 + 4 x ) ^{3}}

\frac{d y}{d x} = \frac{e ^{x}}{y + 2}

\frac{\partial}{\partial x} (x^{2} - 7 x + 12)

\int \frac{x}{x ^{4} - 16} d x

x^{2} y^{^{''}} - 7 x y^{^{'}} + 12 y = 0

\int \frac{x}{cos ^{2} ( x ^{2} )} d x
