limit as x approaches 0 of (-sin(x))/x

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

- 1

Solution steps

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

x \to a lim [c \cdot f (x)] = c \cdot x \to a lim f (x)

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

Apply L'Hopital's Rule

: x \to 0 lim (\frac{cos ( x )}{1})

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

Plug in the value

x = 0

= - \frac{cos ( 0 )}{1}

Simplify

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

= - 1

x \to 0 lim (\frac{b ^{x} - a ^{x}}{x})

x \to \frac{5}{2} lim (\frac{4 x ^{2} - 25}{2 x - 5})

x \to 0 lim (\frac{( 8 + x ) ^{\frac{1}{3}} - 2}{x})

x \to - \infty lim (x^{2} + x)

x \to - 3 lim (x^{2} + 2 x - 5)
