limit as x approaches 0 of ((2-x)^{-1}-2^{-1})/x

x \to 0 lim (\frac{( 2 - x ) ^{- 1} - 2 ^{- 1}}{x})

\frac{1}{4}

Decimal

0.25

Solution steps

x \to 0 lim (\frac{( 2 - x ) ^{- 1} - 2 ^{- 1}}{x})

Simplify

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

= x \to 0 lim (\frac{1}{2 ( - x + 2 )})

Plug in the value

x = 0

= \frac{1}{2 ( - 0 + 2 )}

Simplify

= \frac{1}{4}
