- 1. On two important limits of higher numbers There are two important limits in the first chapter of advanced mathematics, one of which is Lim = (1 + 1 / x) exp (x) = E x→∞ That is Lim = (1 + x) exp (1 / x) = E. in fact, X →∞ is x → + ∞ and X → - ∞, which means that x→0 X → 0 is also x → 0 + and X → 0 -. When x → 0 +, 1 / X → + ∞, and 1 + x > 1, this limit should be the infinite power of a number greater than 1, that is, it should tend to infinity. And X → 0 - should also tend to infinity. Where is wrong?

I know that t = arcsinx, sin on both sides, x equals Sint But there is a theorem that SiNx is infinitesimal. Then isn't Sint sin (Sint)?

- 11. It is known that the solution of the fractional equation a + 2 / x + 1 = 1 about X is a non positive number? "The answer is a is less than or equal to - 1 and not equal to - 2" My question is: If a = - 1, The equation is 1 / x + 1 = 1, The result of solving the fractional equation is x = - 1 So x + 1 = 0, The fractional equation is meaningless Why is a less than or equal to - 1? That's meaningless
