Breaking Classical Rules in Trigonometry: Mission 2050

I am working to develop new method for trigonometry. For example, there are very few angles having exact trigonometric values, however, I could develop exact trigonometric values for all integer angles and regular polygons (few in exception yet) using Precise-Rewritten method. Using Arc-Line method, one can find trigonometric ratios of any arbitrary angles with desired accuracy level. These method are easy for school level too. I could develop the formula for solving n roots of Sin nA too.
