Hello,Is there a the difference between f := t -> 2*t + 1 and f(x)==2*x+1 ? How can I do f o f o f o ...o f = x -> f(f(f(f...f(x)))) ? (I iterate 10 or 100 times)f := x +-> 3*x g := x +-> 2*x+3 It seems impossible to add 2 anonymous functions. I can compute f(x)+g(x) but I can't use (f+g)(x)Can I do (f o g) or can I only compute f(g(x)) = f g x.With mupad (sqrt@@2)(16) and (address@hidden@sin)(PI) compute $2$ and $0$.
