Or are you passing a CAS expression? If you look at how a(f,k) was defined, the f is assumed to be a CAS function (notice the f(t) reference in how a(f,k) is defined). This means you need to pass a CAS function. f(t):=t^2; a(f,1); The CAS allows one to use an expression as a function. (This does not mean that it is good practice.) That is, if we define f as an expression f:=t^2, and then do f(2), it will not only give a warning about using functional notation to evaluate an expression, but also give you the result 4.
