# 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. · 2 years, 11 months ago

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. · 1 year, 3 months ago
