I have a list of functions, i.e.,
funclist = {Sin[x], x^3, Cos[x]^2}.
I can extract each of the functions, like
In[1]:=funclist[[1]]
Out[1]=Sin[x]
, but I don't know how to call these functions with a general argument.
If I type
In[2]:=funclist[t][[1]]
, I get
Out[2]=t
instead of Sin[t] (or t^3 or Cos[t]^2)
What I would like is to extract a function from the list and to call it
with any argument, as it was defined in a standard way:
f[x_]:=Sin[x].
