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

Lösung

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

\frac{2}{x ^{3}}

Schritte zur Lösung

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

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

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

\frac{d}{d x} (1 - \frac{1}{x ^{2}}) = \frac{2}{x ^{3}}

= \frac{2}{x ^{3}}

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

8 x^{2} y^{^{'}} = y^{^{'}} + 8 x e^{- y}

d er i v a t i v e f (x) = - 7 x - \frac{2}{x ^{7}}

\frac{\partial}{\partial x} (arctan (y))
