kubabuk Posted October 6, 2006 Share Posted October 6, 2006 Hi, Unfortunately my math sucks Could you guys give me a hand and convert this equation. ( or at least give me a link to some begginer math website ) I just try to calculate Focal length based on fovx and apperture and don't know how can I extract focal value from atan.... fovx = 2 * atan( (apx/2) / focal ) Many thanks for help Kuba Quote Link to comment Share on other sites More sharing options...
