I'm wondering if the following equation makes sense, and how to solve for .
I found this equation when trying to solve the following problem : http://www.physicshelpforum.com/phys...pacitance.html.
I wanted to find . I realize the solution should be sinusoidal, so something like .
Regarding the problem, when the capacitor halved its energy, I've found out that . So I've found the boundary values and if I find I'm done.
If I find , I have that and so I'm done.
I used Kirchhoff's law of voltage to find . I might have done errors though.
Thank you for any help!
