Hi.

I applied the following transformation to a number, X:

• exp(X) / (1 + exp(X) ) ---> new transformation.
• Written another way: e^x / (1 + e^x) = new transformation

I am raising the natural number e to some number x, and dividing it by (1 + the natural number e raised to some number x). My question is this: how do I undo this transformation? In other words, how do I go from my new transformation back to the original #?

Any help is appreciated; thanks!
