New Method for determination of trigonometric ratios comparing to classical methods. Precise-Rewritten method determines exact value of trigonometric ratios for any angles and for any polygon. It measure exact chord length, values of Sine etc. Being an amateur mathematician, there are few areas where I am trying further improvements not expressed in this book. If someone professional assist me (for their respect supervising me), more areas could be covered in this method. At the end, we can transpose trigonometry to school level from advance study level. Intention of this book (and its main volume Exact Trigonometry: Five New Techniques) is to brought down advance level to school level. I know only after 2050, people realise it.
