Breaking Classical Rules in Trigonometry.
New method to find trigonometric values for one-third angle of a known angle. It suggest a simple method to solve the cubic equation involved in the one-third angles. The method does not use an imaginary number root nor use a complex depression method. Learning new method may be for one hour study. New theorem has introduced to trigonometric values of one-third angle through Crd. 120˚ of Sin 60˚ - route. Same concept has promoted for one-fifth angle as 72˚ and 36˚-route for 5 roots of one-fifth angle. Use of 120˚ ± A, 72˚ ± A, 36˚ ± A, 30˚ ± A, 25.7˚ ± A, 24˚ ± A or 75˚ ± A etc. opens new area for the trigonometry. This book suggest the method for other higher degree equation for solving trigonometric identities. The book solves the complexities faced since 2000 years.
