A NEW APPROACH TO PERIODICITY OF TRIGNONOMETRICAL FUNCTION WITH LIMITS

Understanding the development of Trigonometry is paramount for anyone delving into the realms of mathematics, science and engineering.Trigonometry has undergone a fascinating journey of development over the centuries.By tracing its historical roots and the contribution of luminaries, one gains profound insights into the cultural, intellectual and and scientific advancements of diverse societies. While Trigonometry already reached advanced maturity by 1700s , seminal insights revealing hidden ties binding trigonometric functions and exponential relations throughCalculus vastly expanded the field's utility and influence [1].In mathematics education, Calculus denotes courses of elementary mathematical analysis which are mainly devoted to the study of functions and limits.[2
