Hello,
I know that in Mathematica one can define a function as follows:
f[x_]:=x^2.
The problem is, I get a polynomial from a for loop as an expression p=a*x^n+b*x^(n-1)+... Now I want to evaluate the polynomial at a specific point. I tried to define a function from the polynomial as follows:
f[x_]:=p
and to evaluate
f[2]
which gives me just the polynomial, not it's value at 2.
How can I evaluate this?
Nikola
