When I see cult posts like this , all I can think of is how America will never be the same . It ' s just gonna be another dictatorship . <| sep |> Do those get different results ? <| sep |> They did have a great defense . Last week . <| sep |> Because you made it a big deal for no reason . People didn ' t like your unnecessary correction . The incorrect use of mines no one cares about . You went out of your way to be a jerk for no reason . <| sep |> Sounds to me like it is just calculus by another name . Sorry , but now I don ' t get what the point of your original post was at all . You need to illustrate whatever you ' re trying to say by more substantial examples than polynomials or rational functions say trigonometric or logarithmic functions , but good luck giving a rigorous definition of those without calculus in the first place .
