Homework Help: DEQ/Algebra Question Solve for t

    Solved: DEQ/Algebra Question Solve for t

    1. The problem statement, all variables and given/known data

    I am having difficulty solving for t in the equation below. It is part of a DEQ question that asks at which time t does damped oscillation amplitude fall below a certain value. The relevant equation is below. My main problem is that I am having difficulty solving for t since t is a product of e and the sin function.

    2. Relevant equations

    3. The attempt at a solution
    Trying to take ln of both sides produces the following, which I am still at a loss as how to solve for t.

    Any help is greatly appreciated.

    The only way to solve that for t would be numerically.

    Thank you LCKurtz.

    I thought I was overlooking a simple algebraic solution and was losing hair over this!

    Thanks again!
