limit as x approaches 0 of (sin(4x^2))/x

x \to 0 lim (\frac{sin ( 4 x ^{2} )}{x})

0

Solution steps

x \to 0 lim (\frac{sin ( 4 x ^{2} )}{x})

Apply L'Hopital's Rule

= x \to 0 lim (\frac{cos ( 4 x ^{2} ) \cdot 8 x}{1})

Plug in the value

x = 0

= \frac{cos ( 4 \cdot 0 ^{2} ) \cdot 8 \cdot 0}{1}

Simplify

\frac{cos ( 4 \cdot 0 ^{2} ) \cdot 8 \cdot 0}{1} : 0

= 0
