Proof of Trigonometric functions

Just have a look at the picture. You now don't need any \(\pi\) there!!! I think that trigonometry came this way...

thanks... I thought of deriving a precise value of \(\pi\) to any number of digits, and not by using infinite series, so, with this success, i got to prove these trigonometric functions and calculate the value of many angles.

These triangles already exist. They are called special triangles. If you want to calculate pi then just divide circumference with diameter. It's as easy as that.

@Will-i-am Guo Yeah, you are right... Now part of textbooks... But in order to calculate pi, circumference must be known. No measurement can be precise to even 15 digits. So, these are a good method to find out those.
