\tan law

Unread post by Tahmid Hasan » Tue Dec 21, 2010 6:14 pm

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 ? :?

here's another moderation: :geek:
$$tan A=\frac{4\Delta}{b^2+c^2-a^2}$$

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।
