limit as x approaches 0+of cos(x)*ln(x)

x \to 0 + lim (cos (x) \cdot ln (x))

- \infty

Solution steps

x \to 0 + lim (cos (x) ln (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 (ln (x))

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

x \to 0 + lim (ln (x)) = - \infty

= 1 \cdot (- \infty)

Apply Infinity Property:

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

= - \infty
