But sin (x) --> x as x --> 0 is not a well-defined limit statement, and is in fact entirely meaningless.

As x goes to 0 from the positive side 1/x approaches infinity. But when x goes to 0 from the negative side 1/x goes instead to negative infinity. This means that the limit as x goes to 0 for Cos (x)/x is undefined as the left and right limits do not agree.
