---The problem of infinity and infinitesimal When X - > 0, is | x | / X infinite or infinitesimal? Please tell me why
For the right limit of X - > 0 | x | = x, the limit is 1
For the left limit of X - > 0 | x | = - x, the limit is - 1
The left limit is not equal to the right limit, so the limit does not exist

- 10. As far as I know, we use the ratio limit of two infinitesimals to reflect the speed of two infinitesimals approaching zero. When their ratio limit is equal to - 1, is it equivalent? For example, when x → 0, X and - X are infinitesimals, and the limit of their ratio is equal to - 1, so they tend to zero at the same speed. Theoretically, they are equivalent, but the equivalent definition of Infinitesimal in advanced mathematics textbooks is that the ratio limit is equal to 1, not the absolute value of the ratio limit is equal to 1
