Limit problems of Higher Mathematics Very simple limit problem, limit symbol is not written in Chinese oral What is sin1 / X equal to when x tends to zero from negative When x goes from positive to zero, it doesn't equal 0. What does sin1 / X equal

X tends to zero-
Then 1 / X tends to - ∞
It is obvious that sin (1 / x) oscillates at [- 1,1]
So there is no limit
In the same way
X tends to zero+
Then 1 / X tends to + ∞
Then sin (1 / x) oscillates in [- 1,1]
So there's no limit
