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

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

0

Solution steps

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

Apply the following algebraic property

: a \cdot b = \frac{a}{\frac{1}{b}}, b \neq = 0

ln (3 x) sin (x) = \frac{ln ( 3 x )}{\frac{1}{s i n ( x )}}

= x \to 0 + lim (\frac{ln ( 3 x )}{\frac{1}{s i n ( x )}})

Apply L'Hopital's Rule

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

= x \to 0 + lim (\frac{\frac{1}{x}}{- cot ( x ) csc ( x )})

Simplify

\frac{\frac{1}{x}}{- cot ( x ) csc ( x )} : - \frac{1}{x cot ( x ) csc ( x )}

= x \to 0 + lim (- \frac{1}{x cot ( x ) csc ( x )})

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

= - x \to 0 + lim (\frac{1}{x cot ( x ) csc ( 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

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

x \to 0 + lim (1) = 1

x \to 0 + lim (x cot (x) csc (x)) = \infty

= - \frac{1}{\infty}

Apply Infinity Property:

\frac{c}{\infty} = 0

= 0

x^{2} - x + 4

\frac{d x}{d y} - x y = x^{2} y^{3}

x \to \infty lim (x^{- e})

f (x) = 2 + \frac{1}{x}, (2, 2.5)

\frac{\partial}{\partial x} (2 e^{x^{6} y})
