limit as x approaches 0 of (tan(x))/(2x)

x \to 0 lim (\frac{tan ( x )}{2 x})

\frac{1}{2}

Decimal

0.5

Solution steps

x \to 0 lim (\frac{tan ( x )}{2 x})

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

= \frac{1}{2} \cdot x \to 0 lim (\frac{tan ( x )}{x})

Apply L'Hopital's Rule

= \frac{1}{2} \cdot x \to 0 lim (\frac{sec ^{2} ( x )}{1})

Plug in the value

x = 0

= \frac{1}{2} \cdot \frac{sec ^{2} ( 0 )}{1}

Simplify

\frac{1}{2} \cdot \frac{sec ^{2} ( 0 )}{1} : \frac{1}{2}

= \frac{1}{2}
