f(x)=log{(1+x)/(1-x)}&g(x)=log{(3x+x^3)/(1+3x^2)}then find f[g(x)]


 * (1) This is horribly complex. Most folks can't even get the idea of "function" let alone whatever this thing above is supposed to represent.


 * (2) The notion (informal instruction ?) "find" requires an algorithm to execute "find". Mathematicans figure out how to write and then instantiate the notion "find", not functions. Bill Wvbailey (talk)
