limit as x approaches 0 of (((6+x)^{-1}-6^{-1}))/x

x \to 0 lim \frac{( ( 6 + x ) ^{- 1} - 6 ^{- 1} )}{x}

- \frac{1}{36}

Decimal Notation

- 0.02777 \dots

Solution steps

x \to 0 lim (\frac{( 6 + x ) ^{- 1} - 6 ^{- 1}}{x})

Simplify

\frac{( 6 + x ) ^{- 1} - 6 ^{- 1}}{x} : - \frac{1}{6 ( x + 6 )}

= x \to 0 lim (- \frac{1}{6 ( x + 6 )})

Plug in the value

x = 0

= - \frac{1}{6 ( 0 + 6 )}

Simplify

= - \frac{1}{36}

f (x) = \frac{x ^{2} - 6 x + 12}{x - 4}

x^{2} - 3 x

\int_{0}^{3} \frac{1}{x ^{4}} d x

\int 18 cot^{4} (x) d x

\int y^{2} - 1 d y
