Solved: DEQ/Algebra Question Solve for t
Greetings,
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.
[itex]
\frac{\sqrt{31}}{150}=e^{-2t}\sin(2\sqrt{31}t)
[/itex]
Trying to take ln of both sides produces the following, which I am still at a loss as how to solve for t.
[itex]
\ln{\frac{\sqrt{31}}{150}}=-2t+\ln(\sin(2\sqrt{31}t))
[/itex]
Any help is greatly appreciated.
