this is quite embarrassing: :oops:
$$\tan A= \frac{abc}{R(b^2+c^2-a^2)}$$
has this already been invented?if not(possibility of not being invented is tends to 0),will i get a patent ? :?

:geek: :idea: Wow dude I didn't understand the main concept but if you did invent something and found out no one did before you should send it to be sure and get patent. :!: :geek:

$$tan A=\frac{4\Delta}{b^2+c^2-a^2}$$
P.S.moderated by Sakal Roy. :roll:

Zzzz এইখানে একটা পোস্ট দিয়া আবার মুছে দিল কেন জানি না।

ধরে নিতে পার এইটা তুমি independently আবিস্কার করছ। কিন্তু ব্যাপর হইল একটু কঠিন সমস্যা সমাধান করতে গেলে বুঝবা যে একটা জিনিসকে কত ভিন্ন ভিন্নভাবে প্রকাশ করা যায়। এইটা সাইন এবং কস সূত্রের ভিন্ন প্রকাশ; তবে শ্রীলঙ্কান দলের পুলাপাল একবার এইটা নিয়া কথা বলতেছিল যে তারা নাকি এইটা ব্যবহার করে।

After the competition was over Sri Lankan students had time to enjoy going on excursions mingling with students from other countries, and at times teaching some math to other students – they taught the students from Singapore the Cot Rule!
