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

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

1

Solution steps

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

Apply L'Hopital's Rule

= x \to 0 lim (\frac{e ^{- x}}{cos ( x )})

Plug in the value

x = 0

= \frac{e ^{- 0}}{cos ( 0 )}

Simplify

\frac{e ^{- 0}}{cos ( 0 )} : 1

= 1
