Abstract:
In this paper, new sharp bounds for trigonometric functions are established, by using infinite products as main tools. In particular, alternative
proofs to well-known results on exponential and polynomial bounds are presented, with improvements.
Keywords: Trigonometric function, Bernoulli inequality, infinite product and exponential bounds
