Hello everyone, I'm working on a problem and it turns out that this equation crops up:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]1 = cos^{2}(b)[1-(c-b)^{2}][/tex]

where

[tex]c > \pi[/tex]

Now I'm pretty sure you can't solve for b in closed form (at least I can't), so what I need to do is for some value of c, approximate the value of b to about 5-6 digits of accuracy. I just need tips to head in the right direction. Anything will be useful. Thank you!
