I am trying to take derivatives of a function with parameters in mathematica, here i will post an example:
f[r_] := [eta*cL*(1 - r)*eta*mu (1 - pl) +
eta*cL*(1 - r)*eta*r*(1 - mu) (1 - pl) +
eta*cL*(1 - r)*(1 - eta)*q*(1 - mu) (1 - ph)]/[eta*mu +
eta*r*(1 - mu) + (1 - eta)*q*(1 - mu)]

mathematica is giving me an error...
I dont understand why.
cant it take a function with parameters?
or whats wrong with the syntax that I have?
thanks for your help.
