Hello,
thanks for helping me later with this. However, how could one get px/fx=infinity? (and where can one find that horizontal 8 infinity finure, I don't see it here, where the other buttons are. . .) from lim(fx)=0 and lim (px)= h8 or hor. 8 or horizontal8 or infinity? Is it fx=0/h8 & px = h8 thus that lim(px*1/fx)=lim(0/h8)=lim (h8*h8/0)=h8
Key, fx=f(x), h8=infinity, from horizontally looking 8. . .
