limit as x approaches 0 of (3^x-1)/(4x)

x \to 0 lim (\frac{3 ^{x} - 1}{4 x})

\frac{1}{4} ln (3)

Decimal

0.27465 \dots

Solution steps

x \to 0 lim (\frac{3 ^{x} - 1}{4 x})

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

= \frac{1}{4} \cdot x \to 0 lim (\frac{3 ^{x} - 1}{x})

Apply L'Hopital's Rule

: x \to 0 lim (\frac{ln ( 3 ) \cdot 3 ^{x}}{1})

= \frac{1}{4} \cdot x \to 0 lim (\frac{ln ( 3 ) \cdot 3 ^{x}}{1})

Plug in the value

x = 0

= \frac{1}{4} \cdot \frac{ln ( 3 ) \cdot 3 ^{0}}{1}

Simplify

\frac{1}{4} \cdot \frac{ln ( 3 ) \cdot 3 ^{0}}{1} : \frac{1}{4} ln (3)

= \frac{1}{4} ln (3)

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

x \to 5 lim (\frac{x - 3}{x - 5})

x \to 0 lim (x e^{s i n (\frac{1}{x})})

x \to 0 lim (x^{4} \cdot cos (\frac{3}{x}))

θ \to 0 lim (csc (θ) - cot (θ))
