Homework Help: Solving for t

  1. Sep 20, 2004 #1
    after much stress i now have

    ln(t +1) - t = (-ln399)/4

    i am not sure how you would proceed about isolating for t. i have tried using the exponential and other algebraic tactics but it has been to no avail. some sort of suggestion would be much appreciated.

    There is a thing called "Lambert's W function" that can be used to solve such equations- but it is not an "elementary function". Here is a reference:
