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

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

- \infty

Solution steps

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

\frac{cos ( x )}{x} = cos (x) \frac{1}{x}

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

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

With the exception of indeterminate form

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

x \to 0 - lim (cos (x)) = 1

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

= 1 \cdot (- \infty)

Apply Infinity Property:

c \cdot (- \infty) = - \infty

= - \infty
