I believe that I have discovered a mathematical formula related to trigonometry. It is used for finding the ratio of areas of triangles (not just similar triangles, but all kinds). I asked my Mathematics professor if any such formula for finding ratios exist. He said no. I also counter-checked in many websites. But again no. I believe that my formula can be applied as much as the similar triangles proportionality theorem or maybe more. But the problem is I do not know what further action to take regarding this matter. I don't think patenting is possible but how did the other theorems become very famous? I would like to receive some advice on what i should do.
