In junior high school mathematics, any time of 1 is equal to1; In the field of calculus of advanced mathematics, the infinite power of 1 is uncertain in the limit, which means that if the functions f(x) and g(x) both tend to zero or infinity when x→x0 (or x→∞), then the limit lim [f(x)/g(x)] (x→x0 or x→

Extended reading: square operation.
