2. When solving the limit of this advanced mathematics, Taylor formula is used, that is, the first three lines in my diagram are seeking the limit.
3. When finding the limit of this advanced mathematics, the first step is to change the element, that is, t= 1/x, and turn it into the limit problem of t, and then divide it.
The second step to find the limit of this advanced mathematics is to use Taylor formula, which is the penultimate line in my drawing.
The third step to find the limit of this advanced mathematics is to simplify the above formula, and then you can find the limit.
6. The result of this advanced mathematics limit is equal to 1/2.
The detailed steps and explanations of this advanced mathematics limit are shown in the above figure.
