Question

( theta_{x rightarrow 0} frac{sin ^{2} x(1-cos 2 x)}{x^{4}} )
( lim _{x rightarrow 0} frac{ln ^{2} xleft(2 sin ^{2} xright)}{x^{4}}=frac{1+2 sin ^{4} x}{x+0} )
A kle Kwow the is 11
[
x+2 x
]
( sin frac{1+}{x+0} 2left(frac{sin ^{4} x}{x^{4}}right)=2 x 1^{4}=frac{2}{=} )

# 7. lim SI sin?x(1 – cos 2x) x+0 x4
