Polynomial-Exponential Bounds for Some Trigonometric and Hyperbolic Functions
Recent advances in mathematical inequalities suggest that bounds of polynomial-exponential-type are appropriate for evaluating key trigonometric functions. In this paper, we innovate in this sense by establishing new and sharp bounds of the form <inline-formula><math xmlns="http://www....
