I'm facing the following problem which sounded simple but apparently it is not (at least for me):(adsbygoogle = window.adsbygoogle || []).push({});

I have two sinusoids: different amplitude, different frequency, different phase difference and I want to find the intersection points, which is equivalent to solving the following equation in [tex]\theta[/tex]:

[tex]A_{1}sin(f_{1}\theta+\phi_{1}) = A_{2}sin(f_{2}\theta+\phi_{2})[/tex]

I was not able either to solve the problem in the general case, nor to find a solution around the net.
