The real debate here is whether BF is a troll or an idiot <| sep |> scootatrotbwSo you can catch up to me . <| sep |> A proof ultimately depends on the level of mathematics that you are at , and the tools at your disposal . A relatively simple proof would involve showing that the limsup and liminf are not equal . You could do a proof by contradiction if the given limit exists , and 2 xsin 1 x also has a limit proved by the sandwich theorem , this would imply cos 1 x has a limit which it does not . There are several more ways I can think to go about this , but with absolutely no effort on your part to suggest what you ' ve tried or what tools are at your disposal it would be pointless to go over everything . <| sep |> Does dominate means to penetrate sexually ? It would make so much more sense in context . IE . I will make childbirth very painful , but you will want to have sex with your husband and he will have sex with you . in other words , Child birth will suck , but haha ! You ' re gonna want sex and you ' re gonna have sex and get knocked up and then have the painful birth ! I mean that is a heck of a curse . Where as the translations generally seem to be going off on a tangent . You are going to have painful delivery and oh by the way your husband will boss you around
