It is found that when x approaches infinity, the limit of (sin x)/x is not equal to 1!

Is bounded and infinitesimal.

This limit 1+ 1/x "is not equal to" e!

X tends to 0, and the upper limit of timing is 1.

When x tends to zero negative value, the limit does not exist.

The proof process is very simple. When x tends to 0, let t= 1/x, and the above conclusion can be drawn.
