limit as x approaches 0 of (sin(15x))/x

x \to 0 lim (\frac{sin ( 15 x )}{x})

15

Solution steps

x \to 0 lim (\frac{sin ( 15 x )}{x})

Apply L'Hopital's Rule

= x \to 0 lim (\frac{cos ( 15 x ) \cdot 15}{1})

Plug in the value

x = 0

= \frac{cos ( 15 \cdot 0 ) \cdot 15}{1}

Simplify

\frac{cos ( 15 \cdot 0 ) \cdot 15}{1} : 15

= 15
