derivative of f(x)=x+1+1/(x^2)

Solution

derivative of

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

Solution

- \frac{2}{x ^{3}} + 1

Solution steps

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

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

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

\frac{d x}{d x} = 1

\frac{d}{d x} (1) = 0

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

= 1 + 0 - \frac{2}{x ^{3}}

Simplify

= - \frac{2}{x ^{3}} + 1
