What is the limit of x squared / sin squared x as x approached zero

[From: ] [author: ] [Date: 12-10-19] [Hit: ]

I`m confused about this question... do I have to use an identity, or what

Thanks

Note that:

lim [sin(x) / x] = 1
x->0

So,

lim(x² / sin²(x))
x->0

= lim[1/(sin(x)/x)²]
x-->0

= 1/1² = 1
