limit as x approaches 0 of (5sin(2x))/x

Solution

x \to 0 lim (\frac{5 sin ( 2 x )}{x})

Solution

10

Solution steps

x \to 0 lim (\frac{5 sin ( 2 x )}{x})

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

= 5 \cdot x \to 0 lim (\frac{sin ( 2 x )}{x})

Apply L'Hopital's Rule

: x \to 0 lim (\frac{cos ( 2 x ) \cdot 2}{1})

= 5 \cdot x \to 0 lim (\frac{cos ( 2 x ) \cdot 2}{1})

Plug in the value

x = 0

= 5 \cdot \frac{cos ( 2 \cdot 0 ) \cdot 2}{1}

Simplify

5 \cdot \frac{cos ( 2 \cdot 0 ) \cdot 2}{1} : 10

= 10
