Hello Ralf, > You might learn something from > http://www.aldor.org/docs/HTML/chap23.html#4
It seems it's the pretty method where we build a domain. I want to play with generic functions of type expression -> expression. I use (cos@@100)(1.0) with mupad when I want u100, with u0=1 and u(n+1)=cos u(n) >> 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 ([EMAIL PROTECTED]@sin)(PI) compute $2$ and $0$.
