The domain function of y=sin x is all real numbers. Sine exists in all negative numbers as well as all positive numbers (and is a periodic function meaning it goes in cycles, e.g. it does the same thing over and over). Look under for a link to the graph of sine and cosine and hopefully it will be more clear.
Hope this helps!
PS- about the last answer, it is wrong. The range of sine function is from -1 to 1, not the domain! If you look at the graph (underneath), you'll see that it reaches it's maximum height at 1, and it's minimum at -1.

The domain of a function is all the numbers which can be used as the "input" to the function. The sine function is defined for all negative and positive numbers, so we say the domain of sine is all the (real) numbers.
There are definitions of sine for imaginary and complex numbers, and even for matrices. But this is usually discussed after the first year of college math.

NO,the domain of the sine function are all real numbers

It's all numbers.
Remembre, the domain is the set of all possible "inputs" and the range is the set of all possible "outputs"
When I first saw this question I thought, -1 to 1. I was thinking of the range, the set of all possible outputs.
Sometimes a graph helps you identify range and domain. The domain is the extent to which the graph covers the x axis, and the range is the extent to which the graph covers the y axis.
Since we usually work with functions where y = f(x), this is another way of saying that the domain is the set of all possible x and the range is the set of all possible y.

sin is bounded by 1 and -1
so the range would be... -1 < X < 1
however the domain can travel all the way accross the number line, from -infiniti to +infinity
hope thats what u need!

my answer is right ...
it ranges from -1 to 1
BUT you asked for the domain so that is from negative infinity to positive infinity

All real numbers.

the set of all reals if no interval is noted.
