limit as x approaches 0 of (sin(x/3))/x

x \to 0 lim (\frac{sin ( \frac{x}{3} )}{x})

\frac{1}{3}

Decimal

0.33333 \dots

Solution steps

x \to 0 lim (\frac{sin ( \frac{x}{3} )}{x})

Apply L'Hopital's Rule

: x \to 0 lim (\frac{cos ( \frac{x}{3} ) \frac{1}{3}}{1})

= x \to 0 lim (\frac{cos ( \frac{x}{3} ) \frac{1}{3}}{1})

Plug in the value

x = 0

= \frac{cos ( \frac{0}{3} ) \frac{1}{3}}{1}

Simplify

\frac{cos ( \frac{0}{3} ) \frac{1}{3}}{1} : \frac{1}{3}

= \frac{1}{3}

x \to 0 lim (e^{0})

\frac{d}{d x} (a + b x)

\int \frac{4 x + 3}{x ^{2} + 9} d x

\frac{d ^{2}}{d x ^{2}} (\frac{7}{8 x ^{5}})

\int (4 x^{2} - 2) \cdot x d x
