Functions that exhibit exponential decay behavior?

  1. May 9, 2013 #1
    Any help is appreciated, thanks.
    1. The problem statement, all variables and given/known data
    In my course of differentials equations we were given the task to model a real life system with them, we choosed something that resembles a pendulum.

    2. Relevant equations

    3. The attempt at a solution
    We went to the lab and got experimental data from our system and the resulting data plot looks like a decaying exponential, but using an exponential as our rate of change results in a very complicated system of equations and I was wondering if there exists any other function that exhibits the same behavior or give up and use a linear approximation.

    Many functions, when multiplied by an exponential function, will look similar. Without more details on your problem, it is hard to suggest anything.
