(d^2)/(dx^2)(sqrt(1+x^2))

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

\frac{1}{( 1 + x ^{2} ) 1 + x ^{2}}

Solution steps

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

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

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

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

= \frac{1}{( 1 + x ^{2} ) 1 + x ^{2}}

y^{^{'}} + \frac{y}{6960} = 0.0025862069

\frac{d}{d x} (e^{(- x)})

\int 3 x d x

\frac{d}{d x} ((tan (x))^{s e c (x)})

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