Outrageous . No worse feeling than I got thiHUH ? <| sep |> Tag it NSFL since he obviously died shortly after . <| sep |> Not calculus per se , normally you ' re not going to program statespace controllers in a PLC although some now can . . But math , trigonometry and physics are needed . PLC ' s after all are there to control physical systems , so you have to know math . not necessarily to implement huge algorithms in PLC code , but to come up with controller settings , etc . it will definitely be needed . <| sep |> I was almost convinced until this belief was busted in my own face . I was out with my mum , and we both were catching Pokemon . Several Pidgey appeared . So we decided to divide them to cut Pokeball wastage . She started with the leftmost , and I went the rightmost . One of hers ran . All of mine weren ' t Ditto . I eventually got to the one that ran for her . It was not Ditto either .
