Answer:

  • as written: the limit does not exist
  • sin(x-1)/(x-1) has a limit of sin(1) ≈ 0.841 at x=0

Explanation:

The expression written is interpreted according to the order of operations as ...

sin(x) -(1/x) -1

As x approaches 0 from the left, this approaches +∞. As x approaches 0 from the right, this approaches -∞. These values are different, so the limit does not exist.

Maybe you intend ...

sin(x -1)/(x -1)

This can be evaluated directly at x=0 to give sin(-1)/-1 = sin(1). The argument is interpreted to be radians, so sin(1) ≈ 0.84147098...

The limit is about 0.841 at x=0.
