limit as x approaches 0+of 3tan(x)ln(x)

x \to 0 + lim (3 tan (x) ln (x))

0

Solution steps

x \to 0 + lim (3 tan (x) ln (x))

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

= 3 \cdot x \to 0 + lim (tan (x) ln (x))

Rewrite for L'Hopital

= 3 \cdot x \to 0 + lim (\frac{ln ( x )}{\frac{1}{t a n ( x )}})

Apply L'Hopital's Rule

: x \to 0 + lim (\frac{\frac{1}{x}}{- csc ^{2} ( x )})

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

Simplify

\frac{\frac{1}{x}}{- csc ^{2} ( x )} : - \frac{1}{x csc ^{2} ( x )}

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

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

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

x \to a lim [\frac{f ( x )}{g ( x )}] = \frac{lim _{x \to a} f ( x )}{lim _{x \to a} g ( x )}, x \to a lim g (x) \neq = 0

With the exception of indeterminate form

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

x \to 0 + lim (1) = 1

x \to 0 + lim (x csc^{2} (x)) = \infty

= 3 (- \frac{1}{\infty})

Simplify

3 (- \frac{1}{\infty}) : 0

= 0

x \to 5 lim (x + 10)

x \to \frac{π}{4} lim (cos (x))

x \to 1 + lim (ln (\frac{1}{x - 1}))

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

x \to 2 lim (x)
