limit as x approaches 0 of (9cos(x)-9)/x

x \to 0 lim (\frac{9 cos ( x ) - 9}{x})

0

Solution steps

x \to 0 lim (\frac{9 cos ( x ) - 9}{x})

Apply L'Hopital's Rule

= x \to 0 lim (\frac{- 9 sin ( x )}{1})

Plug in the value

x = 0

= \frac{- 9 sin ( 0 )}{1}

Simplify

\frac{- 9 sin ( 0 )}{1} : 0

= 0
