I'm basically trying to >take the first derivative of (ln(x))^x. Here is my syntax: f = >(ln(x))^x. But then when I evaluate f ', it says nothing but >((ln(x))^x)' which is nothing new. I think the issue here is the expression f' does not clearly specify what variable derivative is taken with respect to. Try either D[Log[x]^x,x] or D[f,x] instead
