 Derivative of E tetra x Forehead Junior Fellow Posts: 3 Threads: 1 Joined: Jul 2011 11/13/2011, 04:21 PM (This post was last modified: 11/13/2011, 04:56 PM by Forehead.)

The question arises, then: how do you compute E raised to the power of each term in a product individually? EDIT: I just realized that there can't be a function $f$ such that $f(a*b) = \exp(a)\exp(b)$ and $f(x) = \exp(x)$. Back to the drawing board... « Next Oldest | Next Newest »
