To find the range and domain of ( \sin(\arctan(x)) ), first consider the domain of ( \arctan(x) ), which is all real numbers. The range of ( \arctan(x) ) is ( (-\frac{\pi}{2}, \frac{\pi}{2}) ), meaning it outputs angles between ( -\frac{\pi}{2} ) and ( \frac{\pi}{2} ).

Then, applying the sine function to these angles, the range of ( \sin(\arctan(x)) ) is between ( -1 ) and ( 1 ).

So, the domain of ( \sin(\arctan(x)) ) is all real numbers, and the range is between ( -1 ) and ( 1 ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
